Abstract
An electrophotographic photoreceptor apparatus is provided and a method of manufacturing such a photoreceptor. The electrophotographic photoreceptor includes a cylindrical substrate. A photosensitive layer is formed on the cylindrical substrate. The photoreceptor has first surface corrugations with a pitch of 0.4 to 0.6 mm in an axial direction of the photoreceptor. Each of the first surface corrugations has a depth of 3.0 to 5.0 μm.
