Abstract: A cylindrical base body of the disclosure includes an outer peripheral surface and an end surface which is connected to the outer peripheral surface. The outer peripheral surface includes a first inclined surface which is inclined inwardly toward the end surface, the end surface includes a second inclined surface which is inclined inwardly toward the outer peripheral surface and is connected to the first inclined surface, and a connecting portion of the first inclined surface and the second inclined surface has a radiused surface.

Abstract: There are provided a method of manufacturing an electrophotographic photoreceptor which achieves excellent enduring characteristics and reduction in occurrence of image defects, a method of manufacturing an image forming apparatus, and an electrophotographic photoreceptor manufacturing apparatus. A method of manufacturing an electrophotographic photoreceptor includes a step of roughening an outer surface of a cylindrical base body so that a surface roughness of the outer surface of the cylindrical base body satisfies Str?0.70, in which Str denotes texture aspect ratio; a step of forming a charge injection blocking layer on the outer surface of the cylindrical base body; a step of forming a photoconductive layer on the charge injection blocking layer; and a step of forming a surface layer on the photoconductive layer.

Abstract: There are provided an electrophotographic photoreceptor which achieves excellent enduring characteristics and reduction in occurrence of image defects, and an image forming apparatus and an electrophotographic photoreceptor manufacturing apparatus. An electrophotographic photoreceptor includes a cylindrical base body; a charge injection blocking layer disposed on the cylindrical base body; a photoconductive layer disposed on the charge injection blocking layer; and a surface layer disposed on the photoconductive layer, the surface layer having a surface roughness defined as: texture aspect ratio Str>0.67.
