PROBLEM TO BE SOLVED: To provide a cylindrical substrate for an electrophotographic photoreceptor capable of obtaining an organic photoreceptor by which good image quality and printing quality can be obtained by restraining the generation of worn particles on the farthest end of the fitting part of the cylindrical substrate having the fitting part for attaching a flange on an end part. SOLUTION: At the end part of the cylindrical substrate 1 to which the fitting part 2 having specified inside diameter and depth for the flange to be attached is provided; a gentle surface part 3 having a gentle surface is provided between the farthest end 2a of the part 2 and the inside surface 1a of the substrate 1. Thus, a corner part where the leading end of a carrying jig inserted in the aperture part of the substrate 1 in the manufacturing process of the photoreceptor may collide can be eliminated, so that the generation of the worn particles is reduced, and the worn particles can be prevented from being mixed when an organic photoconductive layer is formed, and the organic photoreceptor having good quality can be manufactured. |
