Abstract
In the case where an uneven structure is formed on the surface of cylindrical electrophotographic photosensitive members, for the purpose of reducing the variation of the uneven structure between the individual cylindrical electrophotographic photosensitive members even when a large number of cylindrical electrophotographic photosensitive members are continuously processed, an insert is inserted into the interior of a cylindrical electrophotographic photosensitive member including a cylindrical substrate and a surface layer, the surface uneven structure of a molding member is transferred to and formed on the surface of the surface layer of the photosensitive member. The insert includes an abutting part having an outer peripheral surface capable of abutting on the inner peripheral surface of the substrate, a connecting part positioned inside of the abutting part in the radical direction and a shaft part positioned inside of the connecting part in the radical direction.
