Electrophotographic photoreceptor, method for manufacturing the same, and electrophotographic photoreceptor unit, replaceable image-forming unit, and image-forming apparatus including the same
View Patent ↗An electrophotographic photoreceptor includes a substantially cylindrical support and a coating disposed on the support and including a photosensitive layer. The coating has lines due to polishing extending in a direction crossing a circumferential direction of a surface of the photoreceptor in at least part of a region outside an effective region available for image formation in an axial direction.
1. An electrophotographic photoreceptor comprising:
a substantially cylindrical support extending in an axial direction; and
a coating disposed on the support and including a photosensitive layer, an effective region, and an end region outside of the effective region, the end region being adjacent to the effective region in the axial direction, wherein the coating has lines due to polishing extending in a direction crossing a circumferential direction of a surface of the photoreceptor in at least part of the end region and is devoid of polishing portions in the effective region.
2. An electrophotographic photoreceptor unit comprising:
the electrophotographic photoreceptor according to claim 1 ; and
a flat cleaning member that contacts the surface of the photoreceptor, the coating having the lines due to polishing in at least a region contacted by an end of the flat cleaning member.
3. A replaceable image-forming unit comprising the electrophotographic photoreceptor according to claim 1 , wherein the replaceable image-forming unit is used by detachably mounting the replaceable image-forming unit in a body of an image-forming apparatus that forms an image using the photoreceptor.
4. An image-forming apparatus comprising:
a rotatable electrophotographic photoreceptor, the photoreceptor being the electrophotographic photoreceptor according to claim 1 ;
a developing device that supplies a developer to the surface of the photoreceptor; and
a flat cleaning member that contacts the effective region and at least part of the end region outside the effective region to remove an undesired deposit therefrom.
