本発明は電子写真印刷装置のＥＰカートリッジに関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an EP cartridge for an electrophotographic printing device.

け、装置実装時に可動して逃げる構造となっていた。[Prior Art] Conventionally, this type of EP cartridge either does not particularly protect the exposed portion of the photosensitive drum for transfer from the developing area to the cleaning area, or is provided with a cover for protection and is movable when installed in the device. The structure was such that they could run away.

がある。The conventional EP car tricine described above does not particularly protect the exposed part of the photosensitive drum for transfer from the developing area to the cleaning area, so it shakes and gets dirty on the photosensitive drum during or before and after mounting the device before use. , which may cause printing defects. Alternatively, since a cover for protection is provided and the structure is such that it can be moved and escaped when the device is mounted, there is a drawback in that a mechanism for moving the cover to the protection position and the retracted position is required.
本発明の目的は前記課題を解決したＥＰカートリッジを
提供することにある。An object of the present invention is to provide an EP cartridge that solves the above problems.

保持されている。In the figure, an EP cartridge of an electrophotographic printing apparatus according to the present invention includes a photosensitive drum 2 for forming an electrostatic latent image on the circumferential surface, and a developer is attached to the electrostatic latent image on the photosensitive drum 2 to form a latent image. a developing device 3 that makes the photosensitive drum 2 visible; a charger 4 that uniformly charges the circumferential surface of the photosensitive drum 2 in order to form an electrostatic latent image on the surface of the photosensitive drum 2 by irradiating light from a light source (not shown);
A cleaner section 5 for wiping the surface of the photosensitive drum 2 clean after transferring the visible image on the photosensitive drum 2 to recording is held in the cartridge case 6 so as to perform an electrophotographic process.

効果がある。[Effects of the Invention] As explained above, the present invention has a protective sheet that covers the exposed portion of the photosensitive drum and is removably attached to the cartridge case, so that the exposed portion of the photosensitive drum is not covered when operating and handling the EP cartridge before use. This has the effect of preventing printing defects due to stains on the photosensitive drum surface caused by touching it.
