Abstract

PURPOSE:To obtain firmer adhesive strength also to make uniform the length of a free part and to reduce the variation of pressing pressure by face-sticking a blade and a holding member by the first adhesive and also sticking the boundary of a fixed part of the blade and the free part, and the end part of a holding member by the second adhesive. CONSTITUTION:A blade 21 is face-stuck to a holding member 23 by an adhesive layer 24, and also the boundary (c) of a fixed part (a) of the blade 21 and a free part (b), and an end part 23a of the holding member 23 are stuck by an adhesive layer 30. As a result, with respect to the force of a peeling force operating direction (u), the direction was held by a point P up to the present, but the face-adhesion of an (x) area is exemplified to obtain firmer adhesion because the (x) part is a face against the shift of the (u) direction. Moreover, the variance of a (z) part is reduced by utilizing effectively a curvature part R of the tip part 23a of the holding member 23, providing an adhesive layer 30 between its curvature part R and the blade 21, and sticking them. It is because a gap part only is filled up like a capillary phenomenon by converting the adhesive layer 30 to low viscosity by diluting a solvent, etc., and making it flow.

じクリーニング性能を損う場合があった。However, as shown in Fig. M1, especially when there is an adhesive layer 4 on the contact surface of the cleaning member 2 to the image carrier 1 and it is adhered to the support plate 3, the cleaning member 2 is attached to the image carrier 1. The stress applied by the contact pressure is concentrated on the end m portion of the support plate 3, and becomes a force that separates the cleaning member 2 and the image carrier 1. Furthermore, as shown in FIG. 2(a), even if the adhesive surface end P of the support plate 3 has no curvature, it may gradually peel off, and in particular, as shown in FIG. 2(b) K, the support plate 3 If a certain curvature R is present during manufacture, the adhesive point Q at the end of the adhesive 4 and the support plate B will be different in the longitudinal direction y, and the adhesive may peel off more easily than in the case shown in FIG. 2(a). Further, as shown in FIG. 3, when the surface opposite to the surface of the cleaning member 20 in contact with the image carrier 1 is adhered to the support member 3 via the adhesive layer 4, the contact of the cleaning member 2 with the image carrier 1 is Since the pressure varies greatly depending on the length of the free portion, if the adhesive surface end P has a curvature R as shown in the figure, the displacement amount a of the cleaning member 2
The length of the free portion varies depending on the type of cleaning, which may cause variations in contact pressure and impair cleaning performance.

ある。FIG. 5(a) is a detailed sectional view of the cleaner 14 shown in FIG. 4. Note that FIG. 5(b) is a perspective view showing the blade portion. In the figure, after the transfer process, the I-ner remaining and adhering to the surface of the photosensitive drum 1 is scraped off by a rubber blade 21, and a scooping sheet made of a polyester film with a thickness of about 75 μm is placed below the rubber blade 21. 16, it is stored in the container 15a. This scooping sheet 16 is in light contact with the surface of the drum 1, and the degree of contact is such that the residual toner can pass through this sheet.

This prevents the scraped toner from leaking from inside the container 15a to the outside. Further, 17 at the bottom of the cleaning device 14 is a magnet for collecting toner that has fallen to the outside.
A part of the interior is partitioned by a partition plate 18, and the toner dropped by the blade 21 as described above is pushed into a space 20 at the back of the container by a rotating scraping member 19.
By doing so, the apparent density of the toner increases and the container can be made smaller.

The boundary C of the door and the end portion 23a of the holding member 23 are bonded with an adhesive layer 30. As a result, in response to the force in the peeling force acting direction U, conventionally it was held at point P, but in this example, surface adhesion is obtained in the X area, and the Therefore, stronger adhesion can be obtained. Furthermore,
As shown in Figure 6), when the curved part R of the tip 23a of the holding member 23 is effectively utilized and the adhesive layer 30 is provided and bonded between the blades 21 along the curved part R, as shown in Figure 6(a). show z
The variation in parts is reduced. This is done by lowering the viscosity of the adhesive layer '50 by diluting it with a solvent, etc., and then flowing it to fill only the gaps, as in a kind of capillary phenomenon. As the solvent, toluene, monochlorobenzene, ethylene acetate, etc. can be used, and it is particularly preferable to use a nonpolar solvent such as toluene, monochlorobenzene.

剤を用いるのが好ましい。As the adhesive used for the first and second adhesive layers, rubber-like adhesives such as polypropylene, vinyl chloride, urethane, SBR, epoxy-based adhesives, ultraviolet curing resins, and urethanes similar to cleaning materials as mentioned above may be used. A hardened type may also be used. Experimental examples were also obtained in which the hardened type was more resistant to peeling than the rubber-like adhesive. This is thought to be because even if the P part is filled with a rubber-like adhesive, elongation occurs due to external force, albeit slightly, and the strength becomes lower than that of the hardening type. In addition, as the adhesive used for the first and second adhesive layers, both a hardening type adhesive and a rubber-like adhesive can be applied, but a hardening type adhesive is used for the second adhesive layer. is preferable.

Note that the present invention is applicable not only to adhesively holding the blade to the holding member on the surface that contacts the image carrier, but also when adhesively holding the blade on the non-contacting surface, or adhesively holding the blade on the contacting surface and the non-contacting surface, etc. It can also be applied when In addition, as for the grade, as long as it is in contact with the image carrier and can obtain sufficient leaning performance, it is not limited to plate-shaped bodies, but can also be applied to chip-shaped, claw-shaped, rectangular, etc.
As long as the material has elasticity, rubber such as urethane or plastic resin (elastomer) can be used. Further, as the holding member, any suitable member such as an arm-shaped member or a plate-shaped member can be used as long as it can hold the grade in sufficient contact with the image carrier.
