PROBLEM TO BE SOLVED: To provide a manufacturing method capable of obtaining a highly accurate base body for an electrophotographic photoreceptor. SOLUTION: In the case of manufacturing the base body for the electrophotographic photoreceptor by performing an EI method including ironing of a plurality of steps, a plurality of punches 20 and dies 16A, 16B and 16C corresponding to the number of the plurality of steps are prepared. The dies 16A, 16B and 16C are arranged at processing positions B, C and D away in the direction perpendicular to the extending direction of the center axes of the dies. A work 12B is attached on the upper part of the punch 20, and the punch 20 is sequentially moved to the respective processing positions B, C and D. Ironing is performed by the punch 20 and the dies 16A, 16B and 16C at the respective processing positions B, C and D. COPYRIGHT: (C)2004,JPO
