Gap in reveal.In the present embodiment, sealing member 41 is set to sponge, is sticked to the rear end of developing chamber 25 by double faced adhesive tape
On.Developing chamber 25, developer roll 21, powder feeding roller 51, powder outlet cutter 26 is formed integrally as developing device 80.
Illustrate this utility model Delevoping cartridge is how to realize developer roll to keep with photosensitive drums below in conjunction with accompanying drawing 5-7
It is in close contact.
The photosensitive drums box 1 being used together with this utility model development, including framework 15, the left and right sides of framework 15 is provided with
Guide rail 12 is used for guiding Delevoping cartridge to install, and guide rail 12 includes a U-shaped end 12a, and an inclined-plane 12b；Photosensitive drums 11
It is pivotally supported between the two side of framework.
When user along be parallel to fore-and-aft direction apply a power forward to Delevoping cartridge, make Delevoping cartridge install along the X direction
During to photosensitive drums box 1, Delevoping cartridge 2 moves to end 12a along guide rail 12, now the developing chamber 25 of Delevoping cartridge 1 and photoreceptor cartridge
Framework 15 front end abuts, and the elastic component 30 in Delevoping cartridge 1 is compressed, and powder cabin 28 travels forward relative to developing chamber 25.When aobvious
When precalculated position to photosensitive drums box 1 installed by shadow box 2, the elastic component 30 compressed produces the elastic force replying deformation, aobvious
Shadow storehouse 25 and powder cabin 28 will occur relative movement, i.e. powder cabin 28 rearward movement, and developing chamber 25 travels forward, so that Delevoping cartridge
With Elastic Contact in photosensitive drums box so that developer roll 21 is in close contact with photosensitive drums 11.
When Delevoping cartridge 2 installs the precalculated position to photosensitive drums box 1, in order to make Delevoping cartridge 2 more stably be positioned at sense
In light drum box 1, the location division 24 in Delevoping cartridge abuts with plurality of ramps 12b, and Delevoping cartridge 2 is by power F being perpendicular to inclined-plane
Effect, this power F is decomposed into power F1 forward being parallel to fore-and-aft direction, the bullet backward of power F1 and elastic component 30
Power is equal in magnitude, such that it is able to prevent Delevoping cartridge entirety to be moved rearwards by, in order to what Delevoping cartridge was stable is installed in photosensitive drums box.
And the position owing to contacting with powder cabin 28 at developing device 80 arranges and has containment member 41, when developing device 80
When travelling forward, seal member 41 can seal the gap between developing device 80 and powder cabin 28, makes developing device 80 and powder cabin
Still keep being in close contact.
Owing in Delevoping cartridge of the present utility model, developing device can move relative to powder cabin, when Delevoping cartridge is installed to photosensitive drums box
Time, developing device moves to photosensitive drums, and owing to there is the elastic reaction of elastic component so that developer roll elasticity is close to photosensitive
Drum so that being in close contact between developer roll and photosensitive drums, Delevoping cartridge can realize high-quality printing effect.And this utility model
The elastic component of Delevoping cartridge be arranged on the front end of Delevoping cartridge, the urgent thrust that developer roll receives is bigger, compels to push away effect and becomes apparent from.And
And Delevoping cartridge of the present utility model need not additionally to arrange device and receives and compel thrust, save production cost, simplified production work
Skill.
