Abstract
An electrophotographic photoreceptor includes a cylindrical substrate; and a surface layer located on an outer surface of the cylindrical substrate. At least a substrate central portion in a cylindrical axial direction of the outer surface of the cylindrical substrate is formed as a rough surface, and a surface roughness of a surface-layer central portion in the cylindrical axial direction of an outer surface of the surface layer is larger than that of at least one of two surface-layer end portions in the cylindrical axial direction of the outer surface of the surface layer. An image forming apparatus includes the electrophotographic photoreceptor; and a peripheral member capable of contacting a surface of the electrophotographic photoreceptor.
Claims9
An electrophotographic photoreceptor, comprising:
- a cylindrical substrate, at least a substrate central portion in a cylindrical axial direction of an outer surface of the cylindrical substrate having a surface roughness;
- and
- a surface layer located on the outer surface of the cylindrical substrate,
- a surface roughness of a surface-layer central portion in a cylindrical axial direction of an outer surface of the surface layer being larger than a surface roughness of at least one of two surface-layer end portions in the cylindrical axial direction of the outer surface of the surface layer.
