Put, connect with the photosensitive surface in moving direction downstream.Smooth scraper plate 30d is made up of the rubber as elastomer.With solid
Lubricant 30b contact, scrape lubricant, the preferred 3-8 of fineness degree of the brush fiber for the coating brush 30a being coated on photoreceptor 8 but
Neil, density preferably 20,000-10 ten thousand/inch of brush fiber2.If the fineness degree of brush fiber is too thin, coating brush 30a with it is photosensitive
When connecting hair down easily occurs for the surface of body 8, if conversely, brush fiber is too thick, can not improve fibre density.Also, if brush fiber is close
The radical for spending relatively low, then to connect with the surface of photoreceptor 8 brush fiber is reduced.It is thus impossible to make the homogeneous coating of lubricant.Conversely,
If brush fiber density is too high, because the gap of fiber and fiber diminishes, the powder adhesion amount of the lubricant of scraping is reduced, and is caused
Coating weight deficiency.
Then, the coating brush 30a of above-mentioned setting range is set to the fiber thickness degree for being not easy to cause hair down, and can had
Effect is lubricated the fibre density of the homogeneous coating of agent.

Then, enter for the guide part 121,122 being oriented to when assembling photoreceptor 8 to photoreceptor shown in Fig. 6,7
Row explanation.
Figure 10 is the skeleton diagram for representing the 1st guide part 121, the 2nd guide part 122 etc..
In the image processing system of this embodiment, when assembling photoreceptor 8, it is necessary to so that before smooth scraper plate 30d
End is in regular flexure direction (lead) flexure.In addition, it is desirable to the group in a manner of cleaning balde 11a front end does not crimp
Fill photoreceptor.
When assembling photoreceptor in a manner of cleaning balde 11a front end does not crimp, preferably as described in patent document 1
Assembling mode.That is, preferably photoreceptor 8 relative with cleaning balde 11a's to crimp direction substantially opposite direction (in figure left
Side) move and assemble the mode of photoreceptor.As long as smooth scraper plate 30d front end is in the structure of (reverse) flexure in cleaning balde side
Into, so that it may by photoreceptor 8, right side is installed from figure.That is, as long as so that the right side court from figure of photoreceptor 8 moves left and assembled i.e.
Can.Thus, can be while causing the surface of photoreceptor 8 to be moved in smooth scraper plate 30d regular flexure direction, while assembling photoreceptor
8, and, can the direction that crimps of photoreceptor 8 relative with cleaning balde 11a's assemble photoreceptor 8 substantially in parallel.But in this reality
Apply in form so that smooth scraper plate 30d front end is bent in side (lead) opposite with cleaning balde 11a.Therefore, will be photosensitive
Body assembling occasion in right side from figure, smooth scraper plate 30d front end is caused to be bent with regular flexure direction opposite direction.
Then, in this embodiment, the guide part 121,122 of shape shown in Figure 10 is oriented to.It is as a result, flat
Whole scraper plate 30d front end is bent in regular flexure direction (lead), and, cleaning balde 11a front end will not crimp,
Photoreceptor 8 can be assembled.
As shown in Figure 10, the line A of above-below direction in the figure that the 1st guide part 121 passes through from the axis center of photoreceptor relatively, if
Put in side opposite with being configured with each blade member 11a, 30d side.1st guiding parts 121 has spigot surface 121a and bearing surface
121b, the spigot surface the 121a substantially right oblique upper extension in figure, are oriented to, the bearing surface when assembling photoreceptor 8
121b is as described later, when photoreceptor 8 is assembled, photoreceptor is abutted with it.
So, it is opposite with being configured with each blade member 11a, 30d side by the way that 121 relative line A of the 1st guide part is arranged on
Side, when being intended to the right direction assembling from figure of photoreceptor 8 so that photoreceptor 8 abuts with the 1st guide part 121.Thus, can prevent
Only the right side from figure of photoreceptor 8 is assembled, and smooth scraper plate 30d front end is bent with the opposite direction away from rule flexure direction, can be prevented
Only photoreceptor is assembled.
Also, the spigot surface 121a of the 1st guiding parts 121 is the curved surface of arc-shaped, when the diameter of photoreceptor 8 is set into D,
From the photosensitive side front end of the 2nd guide part 122, the distance untill the spigot surface 121a of the 1st guide part 121 turns into D+a2.This
Sample, more than distance of the photosensitive side front end of the 2nd guide part 122 untill spigot surface 121a is the diameter of photoreceptor, therefore,
Photoreceptor 8 can be assembled between the 1st guide part 121 and the 2nd guide part 122.
Also, when photoreceptor 8 is positioned at into framework 100, from the center of photoreceptor 8 to the bearing surface 121b of the 1st guide part 121
Untill distance be (2/D)+a1.Thus, when photoreceptor 8 being positioned at into framework 100, photoreceptor 8 does not contact with bearing surface 121b.
In the above description, it is illustrated with the diameter of photoreceptor, but as long as change above-mentioned diameter D into assembling photoreceptors 8, installation
With the 1st guide part 121 to photoreceptor on part diameter.Such as：1st guide part 121 and photoreceptor
Axle 8a is to occasion, above-mentioned diameter D is the photoreceptor diameter of axle.Also, the brush of photoreceptor 8 and above-mentioned 1st guide part 121 be to occasion,

So, the photoreceptor 8 assembled by the 1st, the 2nd guide part from right oblique upper is as shown in figure 12, with cleaning balde 11a's
Front end and smooth scraper plate 30d front end connect.Also, now, because of the counter-force of cleaning balde, the counter-force of smooth scraper plate and photoreceptor
8 deadweight, photoreceptor 8 is pressed towards right obliquely downward in figure, with the spigot surface 121a and bearing surface 121b of the 1st guide part 121
Intersection X is contacted.Now, the center P after the center P of photoreceptor assembles with respect to photoreceptor 8 is located at right oblique upper.
Now, even if photoreceptor 8 is pushed into towards arrow D1 directions in figure, photoreceptor 8 is also only pushed to the 1st guide part
121, photoreceptor 8 will not move towards arrow D1 directions in figure.Also, due to being the increased side of frictional force with the 1st guide part 121
To therefore, even if photoreceptor arrow D1 directions in figure are pushed into, also suppressing photoreceptor 8 towards turning round clockwise in figure.
Thus, when assembling photoreceptor 8, the surface of photoreceptor 8 can be suppressed and moved towards the flexure side in opposite direction with smooth scraper plate 30d,
The front end that smooth scraper plate 30d can be suppressed is bent with prescribed direction opposite direction.
On the other hand, if being pushed into photoreceptor in arrow D2 directions, photoreceptor 8 moves towards left direction in figure.Thus, make
The direction that crimps for obtaining the photoreceptor 8 relative with cleaning balde 11a's of photoreceptor 8 assembles substantially in parallel.As a result, it can prevent from cleaning
Scraper plate 11a front end curling.If also, photoreceptor 8 is pushed into by arrow D2 directions in figure, the guide part 121 of photoreceptor 8 and the 1st
Separate.Thus, the frictional force of the guide part 121 of photoreceptor 8 and the 1st is eliminated, and the one side of photoreceptor 8 is turned round towards counterclockwise in figure,
It is while assembled.Thus, can be while causing photosensitive surface to be moved in the regular flexure direction of the front end of smooth scraper plate, while will
Photoreceptor 8 is assembled on framework.As a result, smooth scraper plate 30d front end is because of the frictional force with photoreceptor 8 and as regular side
To lead bend, can by photoreceptor 8 be arranged on framework on.
So, in this embodiment, the one side of photoreceptor 8 is moved with surface in the regular flexure direction of smooth screed front end
Mode turn round, while can the direction that crimps of photoreceptor 8 relative with cleaning balde 11a's assemble substantially in parallel.Thus, can make
Cleaning balde 11a, smooth scraper plate 30d is obtained all to bend and assemble well.
Also, in this embodiment, it is configured to：The 121, the 2nd, which is oriented to, by the 1st is oriented to 122 by photoreceptor 8 from arrow D2 directions
Assembling.Thus, when causing photoreceptor 8 to be crimped with cleaning balde 11a and smooth scraper plate 30d, without the movement of switching photoreceptor 8
Direction can be assembled.Thus, easily photoreceptor 8 can be assembled on the framework 100 of cartridge processing 23.
As shown in figure 13, if photoreceptor 8 is assembled on framework 100, photoreceptor 8 is carried out automatically cleaning in arrow F2 directions
Scraper plate 11a power, in arrow F1 directions by the power from smooth scraper plate.Because be subject to from cleaning balde power F2, scrape from smooth
The power F1 and the deadweight Fg of photoreceptor 8 F3 that makes a concerted effort that plate is subject to so that the bearing surface 121b of the guide part 121 of photoreceptor 8 and the 1st
Abut.So, abutted by photoreceptor 8 with the bearing surface of the 1st guide part 121 so that cleaning balde 11a and smooth scraper plate
30d can keep deflected well.Moreover, the photoreceptor 8 that will be assembled in by above-mentioned positioning element 50a, 50b on framework 100
It is positioned on framework 100.
Then, pair blade member to connect with photoreceptor 8 is that an occasion illustrates.
