After this, photoconductor drum 11 surfaces that form electrostatic latent image of all kinds arrive the subtend position with development section 13 respectively.And, to photoconductor drum 11, make image development (developing procedure) on the photoconductor drum 11 from each development section 13 toner supply of all kinds.
After this, 11 surfaces of the photoconductor drum behind the developing procedure arrive the subtend position with intermediate transfer belt 17 respectively.At this, in subtend position separately, primary transfer roller 14 is set, join with intermediate transfer belt 17 inner peripheral surfaces.Then, in primary transfer roller 14 positions, be formed on that each colour toners picture order of photoconductor drum 11 is superimposed to be transferred to (first transfer printing process) on the intermediate transfer belt 17.
Then, photoconductor drum 11 surfaces behind first transfer printing process arrive the 15 subtend positions with cleaning portion respectively.And in cleaning portion 15, the not transfer printing toner that remains on the photoconductor drum 11 is recovered (cleaning process).
After this, photoconductor drum 11 surface orders finish a series of imaging processing of photoconductor drum 11 through the position of feeding lubricating device 16 and the position of the electric portion that disappears (not having diagram).
On the other hand, move according to the diagram direction of arrow on intermediate transfer belt 17 surfaces of image congruencing transfer printing of all kinds on the photoconductor drum 11, arrives secondary transfer roller 18 positions.And in secondary transfer roller 18 positions, the coloured image secondary transfer printing on the intermediate transfer belt 17 is (second transfer printing process) on recording medium P.
After this, intermediate transfer belt 17 surfaces arrive the position of intermediate transfer belt cleaning portion (not having diagram).Then, the not transfer printing toner on the intermediate transfer belt 17 is recovered to intermediate transfer belt cleaning portion, finishes a series of transfer process on the intermediate transfer belt 17.
At this, via transporting guide, transport by registration roller 19 grades from sheet feed section 7 for the recording medium P of secondary transfer roller 18 positions.
At length say, supply with transfer paper P by paper feed roller 8, after transporting guide, be directed to registration roller 19 from the sheet feed section 7 of taking in recording medium P.Make that the recording medium P that arrives registration roller 19 is consistent as the time with the toner on the intermediate transfer belt 17, transport towards secondary transfer roller 18 positions.
After this, transfer printing chromatic colour record images medium P is directed to photographic fixing portion 20.In photographic fixing portion 20, at the clamping part of fixing roller and backer roll, the coloured image photographic fixing is on recording medium P.
Then, the recording medium P after the photographic fixing operation piles up in row's paper portion 5 after being discharged to outside the device body 1 by exit roller 29 as output image, finishes a series of image and forms processing.
Though do not illustrate; The image processing system 1 of this example is provided with and connects the structure of disembarking, and makes the primary transfer roller 14 that joins with colored photoconductor drum 11 with cartridge processing 10Y, 10M, 10C (remove black and white with three colours of the photoconductor drum 11 of cartridge processing 10BK with photoconductor drum 11) and intermediate transfer belt 17 relative photoconductor drums 11 connect to leave removable freely.
And, when forming black white image, connect the structure action of disembarking through making, it is colored with three photoconductor drums 11 to make that three primary transfer rollers 14 leave, and only intermediate transfer belt 17 joins with the photoconductor drum 11 of black and white with cartridge processing 10Bk.Like this; No matter black and white still is row for the national games when forming black white image when forming coloured image with cartridge processing 10Bk (black is used imaging portion); Even and when forming coloured image, the black proportion is high in image mostly, and is general; Compare usage frequency (running rate) height with cartridge processing 10Y, 10M, 10C with colour.
Below, with reference to Fig. 2 and Fig. 3, specify the imaging portion that image forms device.
Fig. 2 be expression as the pie graph of black with the cartridge processing 10Bk (black and white use cartridge processing) of imaging portion, Fig. 3 representes cartridge processing 10Y, the 10M as other imaging portions, the pie graph of 10C (colour is used transaction card).Black and white is with cartridge processing 10Bk and colored different except the look of the toner that is used for imaging process with cartridge processing 10Y, 10M, 10C, and consolidates outside the varying in size of shape lubricant 16b etc., is made up of roughly the same component parts.
Like Fig. 2 and shown in Figure 3; In cartridge processing 10Y, 10M, 10C, 10BK; Carry the photoconductor drum 11 put body as picture, make the charging part 12 that photoconductor drum 11 is charged, make the development section 13 that is formed on the latent electrostatic image developing on the photoconductor drum 11; Reclaim on the photoconductor drum 11 the not cleaning portion 15 of transfer printing toner, the feeding lubricating device 16 of supply of lubricant is accommodated in the housing integratedly on photoconductor drum 11.
At this, carrying the photoconductor drum 11 of putting body as picture is Organophotoreceptors of electronegative property, on drum type electric conductivity supporting mass, is provided with photographic layer etc.
Diagram is omitted, photoconductor drum 11 on as the electric conductivity supporting mass of basic unit the order lamination as the following coating of insulation course, as the charge generating layer and the charge transport layer of photographic layer, protective seam (superficial layer).
Electric conductivity supporting mass (basic unit) as photoconductor drum 11 can use volume resistance 10
10Conductive material below the Ω cm.
The photographic layer of photoconductor drum 11 both can be made as rhythmo structure, also can be made as single layer structure.
At first, explain photographic layer is made as the rhythmo structure occasion that is made up of charge generating layer and charge transport layer.
Charge generating layer is to be the layer of major component with electric charge generation material.Can use known electric charge generation material at charge generating layer.Specifically, as electric charge generation material, can use monoazo pigment, disazo pigment; Trisazo pigment ， perylene pigment, purple cyclic ketones series pigments; Quinacridone pigment, quinone are the condensation polycyclic compound, the squaric acid based dye; The phthalocyanine series pigments, naphthalene phthalocyanine series pigments, Azulene (azulenium) salt based dye etc.Above-mentioned electric charge generation material both can use separately, also can two or more mix use.
For electric charge generation material, as required can be with adhering resin through the use bowl mill, masher, puddle mixer, dispersions such as ultrasound wave are coated on (or on following coating) on the electric conductivity supporting mass with it, form charge generating layer through drying.As the coating process of coating fluid, can use the dip coated method, spraying process, swing rubbing method, nozzle rubbing method, method of spin coating, annular rubbing method etc.The charge generating layer thickness is that the 0.01-5 μ m left and right sides is suitable, about preferred 0.1-2 μ m.
With the dissolving of charge transport material and adhering resin or be dispersed in the appropriate solvent, it is coated on the charge generating layer, can form charge transport layer through drying.Also can add separately or two or more plasticizer levelling agent, antioxidant etc. as required again.The relative adhering resin of charge transport amount of substance 100 weight portions, 20-300 weight portion is suitable, preferred 40-150 weight portion.Again, the thickness of charge transport layer is considered from resolution/response angle, below the preferred 25 μ m.About lower limit, because of differences such as imaging process especially charged potential, more than the preferred 5 μ m.
Below, explain photographic layer is made as the single layer structure occasion.
Can be with above-mentioned electric charge generation material, the charge transport material, dissolving such as adhering resin or be dispersed in the appropriate solvent is coated on it on electric conductivity supporting mass or down on the coating, makes its dry photographic layer that forms single layer structure.Also can not contain the charge transport material, constitute by electric charge generation material and adhering resin.Also plasticizer can be added as required, levelling agent, antioxidant etc. again.
As adhering resin, except the adhering resin that when forming above-mentioned charge transport layer, uses, also may be combined in the adhering resin that uses when forming above-mentioned charge generating layer.Have again, also can use the polymer charge transportation of substances well.Relative adhering resin 100 weight portions, the preferred 5-40 weight of electric charge generation amount of substance portion, the preferred 0-190 weight of charge transport amount of substance portion is more preferably, 50-150 weight portion.
With electric charge generation material, adhering resin and charge transport material use tetrahydrofuran, dioxan together; Ethylene dichloride, the cyclohexane equal solvent forms coating fluid in dispersions such as dispersion machines, uses the dip coated method; Spraying process, the swing rubbing method, coating such as annular rubbing method forms the photographic layer of single layer structure.The photographic layer thickness is that the 5-25 μ m left and right sides is suitable.
The following coating of photoconductor drum 11 is a major component with the resin generally, considers and on above-mentioned resin, uses the solvent application photographic layer, with respect to general organic solvent, hopes to use the high resin of solvent resistance.As this resin, can enumerate polyvinylcarbazole, casein; Water soluble resins such as sodium polyacrylate, polymerization nylon, the ethanol soluble resin of methoxymethyl nylon etc.; Polyurethane, melmac, phenolics; Alkyd-melmac, epoxy resin etc. form the hardening resin of ternary cross-linked structure etc.In following coating, in order to prevent striped, reduce residual electric potential etc., also can add titanium dioxide, silicon dioxide, aluminium oxide, zirconia, tin oxide, the micropowder pigment of metal oxides such as indium oxide.Again, above-mentioned coating is identical with above-mentioned photographic layer down, can use appropriate solvent and rubbing method to form.Following coating film thickness is that the 0-5 μ m left and right sides is suitable.
The protective layer used adhering resin with cross-linked structure of this example forms.Cross-linked structure is the reticulate texture of ternary, uses the reactive monomer in a part, have a plurality of bridging property functional group, makes and uses up or heat energy, makes it produce cross-linking reaction and forms.Has the high abrasion performance of this cancellated adhering resin performance.From electric stability, printability resistance, the life-span angle considers, as above-mentioned reactive monomer, the monomer that also can all or part of use has charge delivery capability.Through using this monomer, in reticulate texture, form the charge transport position, also can give full play to function as protective seam.
As reactive monomer with charge delivery capability; Can use and in a part, contain the charge transport sexual element respectively and have each at least a compound of substituent silicon atom that adds water decomposition property; The compound that in a part, contains charge transport sexual element and hydroxyl; The compound that in a part, contains charge transport sexual element and carboxyl; The compound that in a part, contains charge transport sexual element and epoxy radicals contains the compound of charge transport sexual element and isocyano group etc. in a part.Charge-transporting material with above-mentioned reactive base can use separately, also can two or more also use.
Again, high from electric/chemical stability as the monomer with charge delivery capability, moving of carrier waits consideration soon, also can use the reactive monomer with three arylamine structures.
Have, the viscosity when being coated with in order to invest is adjusted again, and the stress of cross-linking type charge transport layer relaxes, and low-surface-energy quantizes, and reduces functions such as friction factor, also can also can reach the polymerizable monomer and the polymerism oligomer of 2 officials ability with 1 official.As above-mentioned polymerizable monomer, oligomer can utilize known thing.
The polymerization of use heat or light implementation cavity conveying property compound or crosslinked forms protective seam.When carrying out polyreaction, the occasion of only carrying out polyreaction through heat energy is arranged through heat, and the occasion that needs polymerization to begin agent, in order to react preferred interpolation beginning agent effectively with lower temperature.Carry out the polymerization occasion through light, preferably use ultraviolet ray as light, it is considerably less only to carry out reaction through luminous energy, generally and with photopolymerization begins agent.The polymerization of so-called this occasion begins agent, is meant that the ultraviolet ray below the main absorbing wavelength 400nm generates the activated source of free radical or ion etc., makes it begin polymerization.Also can and begin agent with above-mentioned heat and photopolymerization.
Form like this to have a cancellated protective seam abrasion performance high, still, volumetric contraction is big during cross-linking reaction, if thick filmization too then cracks sometimes.This occasion also can be made as rhythmo structure with protective seam, forms the protective seam that is made up of low molecule dispersin polymerization body in lower floor's (photographic layer side), and (face side) forms the protective seam with cross-linked structure on the upper strata.
As stated, in this example,, be provided with hard protective seam on photoconductor drum 11 surfaces; It has cross-linked structure, simultaneously, forms with the adhering resin with charge transport material; Therefore, do not damage function, can prevent because of the film abrasion of cleaning balde to photoconductor drum 11 as photoconductor drum 11.
Charging part 12 is by charging roller 12a, formations such as clearer 12b.Charging roller 12a is the roller member of the elastic layer of resistance in the periphery of conductive metal core coats, feeding lubricating device 16 relatively, be provided in photoconductor drum 11 along the gyratory directions downstream.Again, the relative photoconductor drum 11 of charging roller 12a sets to subtend non-contactly, so that the non-cohesive lubricant that is supplied to photoconductor drum 11 by feeding lubricating device 16.Again, clearer 12b is used to remove dirty dirty on the charging roller 12a, sets to contacting with charging roller 12a.
And, in the charging part 12 that constitutes like this, never illustrated power supply unit to charging roller 12a apply fixed voltage, thus, make that photoconductor drum 11 uniform surface of subtend are charged.
Development section (developing apparatus) 13 mainly by with the developer roll 13a of photoconductor drum 11 subtends; Transport spiral 13b1 with first of developer roll 13a subtend; Transport second of spiral 13b1 subtend through partition member and first and transport spiral 13b2, with the scraper plate 13c formation of developer roll 13a subtend.Developer roll 13a is by being fixedly installed on inside, forming the magnet of magnetic pole at the roller side face, and rotating cover constitutes around the magnet.Upward form a plurality of magnetic poles by magnet at developer roll 13a (cover), upload at developer roll 13a and put developer.
In development section 13, take in the two-component developing agent that constitutes by carrier and toner.
In order to improve image quality, it is the spherical toner more than 0.98 that toner uses circularity." circularity " is the average circularity that is detected by flow formula particle image analytical equipment " FPIA-2000 " (East Asia medical electric corporate system).Specifically, in container, have the water 100-150ml that removes the impurity solid content in advance, in this container, add surfactant (preferred alkyl benzene sulfonate) 0.10.5ml, add again and measure about test portion (toner) 0.1-0.5g as spreading agent.After this, with the about 1-3 of suspending liquid minute the dispersion treatment that ultrasonic disperser disperses this toner, be that 3000-10000/μ l person is arranged on above-mentioned analytical equipment with dispersion liquid concentration, measure toner shape and distribution.
As spherical toner, the toner (crushed toner) of the abnormity that can distort for the shape that the comminuting method that extensively adopted forms in the past carries out heat treated etc. makes its spheroidization, perhaps also can be through the polymerization manufacturing etc.
Use this spherical toner occasion, in the past, take place sometimes to get in the tolerances between cleaning balde 15a and the photoconductor drum 11, push through this gap, it is bad to produce cleaning.But, in this example, through feeding lubricating device 16 with lubricant applying on photoconductor drum 11 surfaces, improve toner fissility (removing property) on the photoconductor drum 11, therefore, can suppress generation and clean bad.
Life-span (reducing the abrasion deterioration) in order to improve cleaning balde 15a is preferably, and is coated with low-friction material at its leading section.
Feeding lubricating device 16 is by solid shape lubricant 16b; The periphery that slips with photoconductor drum 11 and solid shape lubricant 16b is provided with the brush shape pivoting part 16a of bristle; With consolidating the compression spring 16c that shape lubricant 16b energizes towards brush shape pivoting part 16a as the parts of energizing; Make through brushing the plate-shaped member 16d that shape pivoting part 16a supplies to the lubricant thin layerization on the photoconductor drum 11; The support 16e that keeps solid shape lubricant 16b, at the position, downstream of solid shape lubricant 16b and the guide part 16f of brush shape pivoting part 16a subtend, the formations such as vibration part 16g of joining at upstream side position and the brush shape pivoting part 16a of solid shape lubricant 16b.Plate-shaped member 16d brushes shape pivoting part 16a relatively, and in the position, gyratory directions downstream of photoconductor drum 11, photoconductor drum 11 joins with reverse relatively.
On photoconductor drum 11, supply with the lubricant of thin layerization through the feeding lubricating device 16 of such formation.About the formation and the action of feeding lubricating device 16, will specify at the back literary composition.
With reference to Fig. 2 further explain imaging processing recited above.
And frictional electrification is adsorbed on the toner on the carrier, carries with carrier and puts on developer roll 13a.Carry the developer put on developer roll 13a and after this arrive the position of scraper plate 13c.Then, the developer on the developer roll 13a arrives the subtend position (developing location) with photoconductor drum 11 after the position of scraper plate 13c is adjusted in right amount.
After this, in developing regional, the toner in the developer is attached on the electrostatic latent image that is formed on photoconductor drum 11 surfaces.Say that at length form electric field by the sub-image current potential (exposure current potential) of the image portion of irradiating laser L and the potential difference (PD) (development current potential) that is applied between the development bias voltage of developer roll 13a, toner is attached on the sub-image and (forms the toner picture).
After this, the toner that is attached to photoconductor drum 11 at developing procedure almost all is transferred on the intermediate transfer belt 17.And the not transfer printing toner that remains on the photoconductor drum 11 is recovered in the cleaning portion 15 by cleaning balde 15a.
At this, diagram is omitted, and the toner replenishing portion that is located at device body 1 is by changing the ampuliform toner container 28 that constitutes freely, and maintenance/driving toner container 28 turns round, the toner hopper portion to the new toner of development section 13 supplies constitutes simultaneously.In toner container 28, take in new toner (a certain among yellow, magenta, cyan, the black) again.At the inner peripheral surface of toner container 28 (toner bottle), form the spiral fashion projection again.
Along with the consumption of the toner in the development section 13 (existing toner), the new toner in the toner container 28 is from the suitably supply in development section 13 of toner replenishing mouth.Diagram is omitted, the toner consumption in the development section 13 by with the reflective photoelectric sensor of photoconductor drum 11 subtends, and be arranged on the Magnetic Sensor that second of development section 13 transports spiral 13b2 below and detect indirectly or directly.
Specify the formation and the action of the feeding lubricating device 16 (lubricant supply unit) of this example below.
Like Fig. 2; Shown in Figure 3; Feeding lubricating device 16 is by solid shape lubricant 16b; The periphery that slips with photoconductor drum 11 and solid shape lubricant 16b is provided with the brush shape pivoting part 16a (brush shape roller) of bristle; Solid shape lubricant 16b towards the compression spring 16c as the parts of energizing that brush shape pivoting part 16a energizes, is made through brushing the plate-shaped member 16d that shape pivoting part 16a supplies to the lubricant thin layerization on the photoconductor drum 11, keep the support 16e of solid shape lubricant 16b; At the position, downstream of solid shape lubricant 16b and the guide part 16f of brush shape pivoting part 16a subtend, the formations such as vibration part 16g of joining at upstream side position and the brush shape pivoting part 16a of solid shape lubricant 16b.
Brush shape pivoting part 16a is that helical coil is implanted with the bristle of length (hair foot) for 0.2-20mm (preferred 0.5-10mm) scope on base cloth on metal-cored.
If bristle lengths surpasses 20mm, then through wiping with the sliding repeatedly of photoconductor drum 11 between long-term, bristle towards decide direction mao, Gu the scraping getting property and remove the reduction of toner property of shape lubricant 16b from photoconductor drum 11.In contrast, if the not enough 0.2mm of bristle lengths, then the phase relay of the physics of shape lubricant 16b and photoconductor drum 11 is not enough relatively admittedly.Therefore, be preferably, bristle lengths is in above-mentioned scope.
Brush shape relative Fig. 2 of pivoting part 16a and Fig. 3 court be rotating photoconductor drum 11 clockwise, with reverse contact revolution (revolution clockwise of Fig. 2 and Fig. 3).Again; Brush shape pivoting part 16a (bristle) is configured to slip with solid shape lubricant 16b and photoconductor drum 11; Brush shape pivoting part 16a scrapes from solid shape lubricant 16b through revolution and gets lubricant; With this scrape the lubricant of getting be transported to photoconductor drum 11 slip the position after, with this lubricant applying on photoconductor drum 11.
At the back quadrate part of solid shape lubricant 16b, irregular with contacting of solid shape lubricant 16b in order to eliminate brush shape pivoting part 16a, configuration compression spring 16c (parts of energizing) will consolidate shape lubricant 16b and energize towards brush shape pivoting part 16a.Admittedly shape lubricant 16b takes in/remains in the support 16e with compression spring 16c.
In this example, mainly form solid shape lubricant 16b by zinc stearate.At length say,, too apply and be free from side effects to have sufficient lubricity Gu the dissolving of shape lubricant 16b system is the lubricant additive of main composition with zinc stearate, very suitable.
Zinc stearate is typical layered crystal.Laminated crystalline has the layer structure of amphipathic molecule self-organization, if apply shearing force, crystal is prone to split and slide along interlayer.Therefore, can make photoconductor drum 11 surperficial low-friction coefficientizations.That is, cover photoconductor drum 11 layered crystal outwardly equably, can cover photoconductor drum 11 surfaces effectively through minor amounts of lubricants owing to receive shearing force.
As solid shape lubricant 16b, except zinc stearate, can also use barium stearate, ferric stearate, nickel stearate, cobaltous octadecanate, copper stearate, strontium stearate, calcium stearate etc. have the material of stearic acid-base.Again, also can use identical fatty acid-based zinc oleate, barium oleate, plumbi oleas, zinc palmitate, palmitic acid barium, palm lead plumbate.In addition, as fatty acid-based, it is sad to use, leukotrienes etc.Have again, also can use candelilla wax, Brazil wax, rice wax, haze tallow, big leaf oil, close wax, waxes such as sheep oil.Above-mentioned substance is prone to become the solid shape lubricant of organic system, and is good with the compatibility of toner.
Be coated on photoconductor drum 11 surfaces if will consolidate shape lubricant 16b through brush shape pivoting part 16a; The lubricant applying of powder shaped is on photoconductor drum 11 surfaces; But lubricity can not be given full play under this state; Therefore, scraping tabular parts 16d (thin layer scraper plate) plays as making lubricant homogenization functions of components.Scrape tabular parts 16d through this, on photoconductor drum 11, carry out the membranization of lubricant, greasy property is given full play to its lubricity.
At this moment, the lubricant of the powder shaped through brush shape pivoting part 16a coating is a micropowder, through scrape tabular parts 16d with the molecular film level in photoconductor drum 11 upper filmizations.
Below, be described in detail in the formation/action of the feeding lubricating device 16 that has characteristic in this example.
With reference to Fig. 2, Fig. 3, Fig. 4 (a); Feeding lubricating device 16 at this example; Along the gyratory directions of brush shape pivoting part 16a, from and solid shape lubricant 16b slip the position to and photoconductor drum 11 slip the part the position, be provided with guide part 16f; Brush the peripheral part of shape pivoting part 16a relatively, the devices spaced apart subtend.
Say that at length guide part 16f brushes the gyratory directions of shape pivoting part 16a relatively, with the position of the side in the downstream of solid shape lubricant 16b as basic point, and photoconductor drum 11 slip the part between the position, separate the minim gap subtend about 0.5-2mm.That is, guide part 16f is in the position of slipping from brush shape pivoting part 16a and solid shape lubricant 16b, and the certain limit in downstream is brushed the peripheral part of shape pivoting part 16a relatively, separates minim gap, sets to be concentric circles arcuation roughly, do not form big space.
Through this structure, even in the position, downstream of solid shape lubricant 16b,, can make this lubricant staying of circling in the air on guide part 16f because of brush shape pivoting part 16a lubricant circles in the air, carry again and put brush shape pivoting part 16a.
At length say; Among cutting the lubricant of getting by brush shape pivoting part 16a from solid shape lubricant 16b; Carry to put on brush shape pivoting part 16a and transport, slipping the position, be not coated on the photoconductor drum 11 with photoconductor drum 11; Position in brush shape pivoting part 16a and the downstream of slipping the position of solid shape lubricant 16b; Because of the bristle of brush shape pivoting part 16a is returned to the lubricant that the impetus when erecting state is circled in the air from deflected, do not disperse to the below of feeding lubricating device 16, and tackle by guide part 16f.And; The surface that is trapped in guide part 16f is (between guide part 16f and the brush shape pivoting part 16a; The zone that the dotted line of Fig. 4 (a) surrounds) lubricant (lubricant circles in the air) carries once more to be put on brush shape pivoting part 16a; With the original lubricant of putting on brush shape pivoting part 16a that carries, be transported to photoconductor drum 11 and slip the position, be coated on the photoconductor drum 11.
Therefore, cut the lubricant of getting by brush shape pivoting part 16a from solid shape lubricant 16b and can not be coated with (supply) effectively lavishly to photoconductor drum 11.
In this example, with the position of the side in the downstream of solid shape lubricant 16b as basic point, and photoconductor drum 11 slip the part between the position, guide part 16f is set.
In contrast, also can be with the position of the side in the downstream of solid shape lubricant 16b as basic point, and photoconductor drum 11 slip whole (in fact up near the positions of slipping the position) between the position, guide part 16f is set.
Again, also can be with the position of the side (side of support 16e) in the downstream of the support 16e that keeps solid shape lubricant 16b as basic point, and photoconductor drum 11 slip local between the position or all, guide part 16f is set.In fact support 16e makes solid shape lubricant 16b connect airtight maintenance, therefore, even be that basic point is provided with guide part 16f occasion with the side of support 16e, also can bring into play making the effect of lubricant staying of guide part 16f of circling in the air.
In this example, guide part 16f forms with sheet metal, also plays the function of scraping the holding member of tabular parts 16d as maintenance.
Thus, the constituent part number of feeding lubricating device 16 is few, can obtain above-mentioned effect.Have again, in the downstream of slipping the position of brush shape pivoting part 16a and solid shape lubricant 16b, can be with by solid shape lubricant 16b; Brush shape pivoting part 16a; Guide part 16f, photoconductor drum 11, and scrape the space that tabular parts 16d surrounds and be made as confined space; The lubricant that therefore, can suppress to circle in the air escapes to the undesirable condition of guide part 16f below.
At this; Feeding lubricating device 16 at this example; Relatively with the position of slipping of solid shape lubricant 16b, in the position of the gyratory directions upstream side of brush shape pivoting part 16a, the bristle that is provided with brush shape pivoting part 16a joins; Remove vibration part 16g attached to the attachment on the bristle (mainly being to remove) by the not transfer printing toner of brush shape pivoting part 16a recovery by cleaning balde 15a.Vibration part 16g is the plate-shaped member that is made up of thin stainless steel etc., sets to be its front end several millimeter of bristle of nipping.
And; On the photoconductor drum 11 that reclaims by brush shape pivoting part 16a not the attachment of transfer printing toner etc. in the position of vibration part 16g; Scrape by vibration part 16g machinery, stockpile and stockpile the space (at Fig. 2, among Fig. 3 at feeding lubricating device 16; The below of cleaning portion 15, the rightward space of support 16e).Therefore, when with the position of slipping of solid shape lubricant 16b, brush shape pivoting part 16a cuts when getting lubricant, attachment such as transfer printing toner is not cleaner state almost not attached on this bristle, improves lubricant and cuts and get efficient.
And in this example, vibration part 16g and support 16e form together and make solid shape lubricant 16b isolated with the space of the gyratory directions upstream side of brush shape pivoting part 16a.Specifically, the root of vibration part 16g and support 16e connect airtight and are being held.
Through this structure, the attachments such as not transfer printing toner that can suppress to be removed by vibration part 16g are at the position of solid shape lubricant 16b and the defective mode of mix lubricant.That is, the high lubricant of purity that is not mixed with transfer printing toner not etc. carries to be put on brush shape pivoting part 16a, improves the supply property of lubricant to photoconductor drum 11.
In this example, also can a plurality of through holes alongst be set at vibration part 16g.This occasion; Make that the aperture of through hole is littler than toner particle diameter; Bigger than lubricant particle diameter, be not coated on photoconductor drum 11 and the minute quantity lubricant that remains in brush shape pivoting part 16a can't help to tremble part 16g and removed, and through through hole once more to photoconductor drum 11 coatings.
With reference to Fig. 4 (a); In this example; When seeing with the cross section of the rotary middle spindle quadrature of brush shape pivoting part 16a, solid that shape lubricant 16b forms is rectangular-shaped, and the face that slips that slips with brush shape pivoting part 16a forms relatively the imaginary line quadrature through the rotary middle spindle of brushing shape pivoting part 16a; Simultaneously, this slips the gyratory directions upstream side displacement D of the center of face towards brush shape pivoting part 16a.Specifically, Gu shape lubricant 16b makes the center of the face that slips towards the upstream side configuration of staggering, amount of movement D is 1-2mm.
Through this formation; What be prone to guarantee to brush relatively shape pivoting part 16a and solid shape lubricant 16b slips the position in the space downstream, between guide part 16f and the brush shape pivoting part 16a, and performance makes the lubricant staying of the circling in the air effect at above-mentioned guide part 16f really.
Again; In this example, solid shape lubricant 16b is energized the foot of the feasible shape of brush relatively pivoting part 16a through compression spring 16c (parts of energizing); Oblique lower position at the brush shape pivoting part 16a of the gyratory directions upstream side of brush shape pivoting part 16a slips with bristle.That is, Gu shape lubricant 16b is at Fig. 2, among Fig. 3, in the oblique lower position contact in the right side of brush shape pivoting part 16a.
Again, photoconductor drum 11 is the topmosts of brush shape pivoting part 16a relatively, in the oblique upper position of the brush shape pivoting part 16a of the gyratory directions upstream side of brush shape pivoting part 16a, slip with bristle.That is, photoconductor drum 11 is at Fig. 2, among Fig. 3, in oblique upper position, the left side contact of brush shape pivoting part 16a.
Have, brush shape pivoting part 16a constitutes towards the gyratory directions equidirectional (Fig. 2, Fig. 3 are clockwise) with photoconductor drum 11 and turns round again.
Through this formation; What be prone to guarantee to brush relatively shape pivoting part 16a and solid shape lubricant 16b slips the position in the space downstream, between guide part 16f and the brush shape pivoting part 16a, and performance makes the lubricant staying of the circling in the air effect at above-mentioned guide part 16f really.
In this example, the gap of brush shape pivoting part 16a and guide part 16f becomes roughly certain.
In contrast, shown in Fig. 4 (b), also can be provided with and stockpile the 16f1 of portion (recess), make with the gap change of brush shape pivoting part 16a big in the part of guide part 16f (near solid shape lubricant 16b side).Stockpile the 16f1 of portion through such setting, the lubricant that circles in the air the position from slipping of solid shape lubricant 16b is prone to concentrate to be trapped in stockpile the 16f1 of portion, and performance makes the lubricant staying of the circling in the air effect at above-mentioned guide part 16f really.
At this; As above-mentioned Fig. 1 is illustrated; In the image processing system 1 of this example, as black with the black of imaging portion with cartridge processing 10BK relatively as the colour of other imaging portions with cartridge processing 10Y, 10M, 10C, be provided in the downstream of the moving direction of intermediate transfer belt 17.Have, black is colored relatively with cartridge processing 10Y, 10M, 10C (other imaging portions) with cartridge processing 10BK (black is used imaging portion) again, and the capacity that constitutes the lubricant that remains on feeding lubricating device 16 is many.
Specifically; With reference to Fig. 2 and Fig. 3, black constitutes bigger with the solid shape lubricant 16b of the feeding lubricating device 16 of cartridge processing 10Y, 10M, 10C (other imaging portions) than colour with the solid shape lubricant 16b size of the feeding lubricating device 16 of cartridge processing 10BK (black is used imaging portion).
Like this,, compare with cartridge processing 10Y, 10M, 10C, can make that lubricant is supplied with T.T. of photoconductor drum 11 is long, therefore, can make photoconductor drum 11 deteriorations postponements in period with colour through strengthening the solid shape lubricant 16b of black with cartridge processing 10BK.Therefore, compare with cartridge processing 10Y, 10M, 10C, can make the high black of usage frequency with cartridge processing 10BK long lifetime with colour.
On the other hand, like this, through strengthening solid shape lubricant 16b, black with the height H 1 of the vertical direction of cartridge processing 10BK than the height H 2 of colored vertical direction with cartridge processing 10Y, 10M, 10C (H1＞H2) greatly.Specifically, black is with the outstanding downwards solid shape lubricant 16b augmenting portion of the feeding lubricating device 16 of cartridge processing 10BK.
But in the image processing system 1 of this example, among a plurality of cartridge processing 10Y, 10M, 10C, the 10BK, black is provided in end position (downstream) with cartridge processing 10BK.Thus, at the lower position of a plurality of cartridge processing 10Y, 10M, 10C, 10BK, can guarantee centralized space.Specifically, in this example, with reference to Fig. 1, write section 6 be arranged on a plurality of cartridge processing 10Y, 10M, 10C, 10BK near, make and do not interfere with the feeding lubricating device 16 of cartridge processing 10BK with black.
Through this formation, can make feeding lubricating device 16 (Gu shape lubricant 16b) large scaleization, even black with cartridge processing 10BK long lifetime occasion, can not increase the vertical direction height of image processing system 1 yet.
Again, with reference to Fig. 2 and Fig. 3, in this example, black is compared with cartridge processing 10Y, 10M, 10C (other imaging portions) with colored with cartridge processing 10BK (black is used imaging portion), and the external diameter that constitutes brush shape pivoting part 16a is big.Specifically, black uses the brush shape pivoting part 16a of cartridge processing 10BK to use the bristle lengths of the brush shape pivoting part 16a of cartridge processing 10Y, 10M, 10C all to be 0.2-20mm with colored, and the metal-cored external diameter of web-like bristle is different.
Through making that like this external diameter of brush shape pivoting part 16a (metal-cored) is big, brush shape pivoting part 16a is difficult to produce distortion, is difficult to produce the defective mode that the coating that is coated on the lubricant on the photoconductor drum 11 irregular (deviation) causes.
And, big through constituting brush shape pivoting part 16a external diameter, black with the height H 1 of the vertical direction of cartridge processing 10BK than the height H 2 of colored vertical direction with cartridge processing 10Y, 10M, 10C (H1＞H2) greatly.But; In the image processing system 1 of this example, among a plurality of cartridge processing 10Y, 10M, 10C, the 10BK, black is provided in end position (downstream) with cartridge processing 10BK; Therefore, image processing system 1 whole vertical direction height can not increase.
Again; With reference to Fig. 2 and Fig. 3; In this example; Black is compared with cartridge processing 10Y, 10M, 10C (other imaging portions) with colored with cartridge processing 10BK (black is used imaging portion), forms the angle of joining of scraping tabular parts 16d (connect the center of photoconductor drum 11 and with the line segment of the connecting position of scraping tabular parts 16d and scrape the angle that tabular parts 16d forms) greatly.
Specifically, the colored angle θ 2 that joins that scrapes tabular parts 16d with cartridge processing 10Y, 10M, 10C is set at about 90 degree, and black is set in the scope of 91-160 degree with the angle θ 1 that joins of the tabular parts 16d of scraping of cartridge processing 10BK.
Like this, black with cartridge processing 10BK in, the angle θ 1 that joins that scrapes tabular parts 16d is set at the obtuse angle, therefore, the frictional resistance of scraping the relative photoconductor drum 11 of tabular parts 16d is little.Therefore, because of the abrasion deterioration of slipping the both sides' parts that cause of brush shape pivoting part 16a and photoconductor drum 11 is postponed, and can reduce the driving torque of photoconductor drum 11.
And, be the obtuse angle through the angle initialization that joins that will scrape tabular parts 16d, black is colored big with the vertical direction height of cartridge processing 10Y, 10M, 10C with the vertical direction aspect ratio of cartridge processing 10BK.But; In the image processing system 1 of this example, among a plurality of cartridge processing 10Y, 10M, 10C, the 10BK, black is provided in end position (downstream) with cartridge processing 10BK; Therefore, image processing system 1 whole vertical direction height can not increase.
Again; With reference to Fig. 4 (a); In this example; Be arranged on black and coloredly compare with being arranged on the feeding lubricating device 16 of cartridge processing 10Y, 10M, 10C (other imaging portions) with the feeding lubricating device 16 of cartridge processing 10BK (black is used imaging portion), the solid angle [alpha] of joining of shape lubricant 16b (connect center and the brush shape pivoting part 16a of photoconductor drum 11 straight line and center through brushing shape pivoting part 16a, with the vertical formed angle of straight line of the face that slips of shape lubricant 16b admittedly) greatly.
Through this formation; The solid shape lubricant 16b that black is used compares with the solid shape lubricant 16b of colour usefulness; Even receive counter-force from photoconductor drum 11,16a produces deflection at brush shape pivoting part, also is difficult to produce because of this deflection causes the axial lubricant of revolution cut the deviation of the amount of getting; Therefore, can further improve the life-span of photoconductor drum 11.
And through setting the angle [alpha] of joining of big solid shape lubricant 16b, black is big with the height of the vertical direction of cartridge processing 10Y, 10M, 10C with the aspect ratio colour of the vertical direction of cartridge processing 10BK.But; In the image processing system 1 of this example, among a plurality of cartridge processing 10Y, 10M, 10C, the 10BK, black is provided in end position (downstream) with cartridge processing 10BK; Therefore, image processing system 1 whole vertical direction height can not increase.
Again; With reference to Fig. 5; In this example; Be arranged on black and compare with the feeding lubricating device 16 of cartridge processing 10Y, 10M, 10C (other imaging portions) with being arranged on colour with the feeding lubricating device 16 of cartridge processing 10BK (black is used imaging portion), the angle that forms the leading section (linking part) of scraping tabular parts 16d is big.
Specifically, shown in Fig. 5 (a), the angle initialization of the leading section of scraping tabular parts 16d that black uses is about 120 degree.In contrast, the angle initialization of the colored leading section of scraping tabular parts 16d that uses is about 90 degree.
Through this formation, the tabular parts 16d that scrapes that black is used compares with the tabular parts 16d of scraping of colour usefulness, even usage frequency is high, leading section also is difficult to produce abrasion, further improves the transaction card reason life-span.
In order further to improve the life-span of scraping tabular parts 16d, be preferably, at its leading section coating low-friction material.
At this, in this example, black can use the different persons of kind with the solid shape lubricant 16b of cartridge processing 10BK (black is used imaging portion) respectively with colored solid shape lubricant 16b with cartridge processing 10Y, 10M, 10C (other imaging portions).Specifically; As the solid shape lubricant 16b of colour with cartridge processing 10Y, 10M, 10C; Can use zinc stearate to form,, can use mixed nitride boron formation at least in zinc stearate as the solid shape lubricant 16b of black with cartridge processing 10BK (black is used imaging portion).
Through using the solid shape lubricant 16b that constitutes by zinc stearate, as stated, can obtain the sufficient lubricity on photoconductor drum 11 surfaces.And,, can obtain the lubricity more fully on photoconductor drum 11 surfaces through using the solid shape lubricant 16b that constitutes by the zinc stearate that is mixed with boron nitride.Therefore, can further prolong the life-span of black with the photoconductor drum 11 of cartridge processing 10BK.
Again, with reference to Fig. 2 and Fig. 3, in this example, black is compared with cartridge processing 10Y, 10M, 10C (other imaging portions) with colored with cartridge processing 10BK (black is used imaging portion), and the gap that forms between charging roller 12a and the photoconductor drum 11 is little.
Specifically, and colour is with the charging roller 12a of cartridge processing 10Y, 10M, 10C and the gap delta 2 between the photoconductor drum 11, and black is set at little with the charging roller 12a of cartridge processing 10BK and the gap delta 1 between the photoconductor drum 11.
Like this, black with cartridge processing 10BK in, the gap delta 1 that is set between charging roller 12a and the photoconductor drum 11 is smaller, therefore, can reduce the charging roller 12a ozone generating capacity in when discharge.Have again, less through the gap delta 1 between charging roller 12a and the photoconductor drum 11 is set at, can reduce the height of black with the vertical direction of cartridge processing 10BK.
As stated; According to this example, relatively with the position of slipping of consolidating shape lubricant 16b, in the gyratory directions downstream of brush shape pivoting part 16a; Be provided with guide part 16f; Relatively the peripheral part of brush shape pivoting part 16a separates the minim gap subtend, therefore, can scrape the lubricant of getting from solid shape lubricant 16b by brush shape pivoting part 16a and not have effectively and supply to lavishly on the photoconductor drum 11 (putting body as carrying).
In this example, make each of imaging portion (photoconductor drum 11, charging part 12; Development section 13, cleaning portion 15, feeding lubricating device 16) integrated; Constitute cartridge processing 10Y, 10M, 10C, 10BK, be embodied as the miniaturization of picture portion, improve maintenance operation property.
In contrast, can each one of imaging portion (photoconductor drum 11, charging part 12, development section 13, cleaning portion 15, feeding lubricating device 16) be made as the cartridge processing component parts yet, constitute respectively to change and be arranged on freely in the device body 1 with monomer.This occasion also can obtain the effect identical with this example.
Again; In this example; The present invention is applicable to the image processing system of the development section 13 of bi-component visualization way that carry to use two-component developing agent, certainly, also can be suitable for the present invention for the image processing system of the development section 13 that carries the single component development mode of using monocomponent toner.
In this example, the present invention is applicable to the coloured image of the tandem type that uses intermediate transfer belt 17 forms device again.But; Even the coloured image for the tandem type that uses the transfer printing moving belt forms device (with transfer printing moving belt subtend; Be set up in parallel a plurality of photoconductor drums, with the toner on the photoconductor drum as the device of superimposed transfer printing on the recording medium that transports by the transfer printing moving belt) also can be suitable for the present invention.And, even this occasion also can obtain the effect identical with this example.
Again, in this example, black is compared with cartridge processing 10Y, 10M, 10C (other imaging portions) with colored with cartridge processing 10BK (black is used imaging portion), and the moving direction of relative intermediate transfer belt 17 is provided in downstream.In contrast, black is compared with cartridge processing 10Y, 10M, 10C with colour with cartridge processing 10BK, and the relative moving direction of intermediate transfer belt 17 also can be provided in upstream side.And, even this occasion also can obtain the effect identical with this example.
Again; In this example; The present invention is applicable to the feeding lubricating device 16 that carries photoconductor drum 11 supply of lubricant of putting body as picture, still, certainly; Carry the feeding lubricating device of putting the body supply of lubricant feeding lubricating device of intermediate transfer belt 17 supply of lubricant (for example to) for the picture beyond the photoconductor drum 11, also can be suitable for the present invention.And,,, also can obtain the effect identical with this example through guide part 16f is set even this occasion is identical with this example.
Above with reference to description of drawings example of the present invention, but the present invention is not limited to above-mentioned example.In technological thought scope of the present invention, can do all changes, they all belong to protection scope of the present invention.
