へ挿入することができる。The method for attaching the photosensitive drum 5 to the upper housing will be explained below using the fifth example. FIG. 5 is a vertical sectional view of the process kit. In the figure, the photosensitive drum 3 has seven front lunges 42.
The end flange 45 is fixed. The photosensitive drum 5 is first inserted into the upper housing 19 from the bottom as shown by arrow A.
Insert it into the drum 1, then slide it to the right @, and press the drum 3.
The 7 langes 45 on the back side of the housing 19 are fitted together. By inserting the photosensitive drum 3 into the upper body 1 in this way, it can be used without being disturbed by the image roller 15, rubber blade 17, shield plate 22, or discharge device 4, which have been installed in advance. The screwdriver 3 can be inserted into the installation position without damaging the surface.

Since the photosensitive drum 3 can be assembled after the Teiden wire 25 is assembled, the inspection process is simplified. That is, after assembling the above-mentioned parts other than the first sensing drum 5 into the upper casing 19, first inspect the tool drive, electric potential, etc., and when they pass, proceed to other installations! The tool drum can be replaced with the actual photosensitive drum 3 without changing b, and by installing the photosensitive drum 6 after the moth, it is possible to reduce the chances of the drum 3 being scratched.

・クリーナ等の筐体を接合して一体化する事によって、
製造過程の短縮を実現することができしいてはコストダ
ウンを達成する拳が出来る。As explained above, according to the Honjitsu Jllii example, the process killer, which has an integrated housing for the developing device, cleaner, etc. disposed around the photosensitive drum, has conventionally been used to position individual parts with respect to the drum. Since the casing of the process kit can be positioned with the precision of one, it becomes easy to position each component. Furthermore, by joining and integrating the housings of the developer, cleaner, etc., which were separate parts,
If the manufacturing process can be shortened, it will be possible to achieve cost reduction.

成ｇ装置を提供するこができる。Further, as the cost of the kit decreases, for example, the process kit can be made disposable, making it possible to replenish the developer, collect waste toner, and replace the charging wire at the same time when replacing the photosensitive drum. In addition, since the operator does not have to scale the imager cleaner etc. each time the photoreceptor is replaced, it is possible to reduce toner scattering.9 Furthermore, the area around the photoreceptor drum is completely covered. Therefore, there is less risk of injury. In addition, the casing can be divided into parts so that they can be joined during assembly, and the casing can be finally joined and integrated after the photosensitive drum has been installed, making inspection during manufacturing easier. The photosensitive drum can be easily replaced when collecting and recycling the used process kit. As described above, according to this embodiment, it is possible to provide an image forming apparatus having a process kit that is excellent in not only operability but also productivity.
