Abstract:
1. A surface abrading method of an electrophotographic photoreceptor comprising at least a photosensitive layer on an electrically conductive substrate, the method comprising abrading a surface of the photosensitive layer with an abrading member entrained about a backup roll with feeding the abrading member and rotating the electrophotographic photoreceptor, while moving the abrading member parallel to a rotating shaft of the electrophotographic photoreceptor with bringing the abrading member into contact with the surface of the photosensitive layer, wherein the abrading member comprises a solid body on a backing material, the solid body contains abrasive grains and is provided on a side of the backing material which is to be brought into contact with the photosensitive layer surface, and a top face of the solid body which is to be brought into contact with the photosensitive layer surface exhibits a surface roughness (Ry) of from 4.0 to 8.0 μm.
