PURPOSE:To provide the photosensitive drum of a low cost by allowing not flanges formed by using a costly conductive resin material having the coefft. of thermal expansion approximate to the coefft. of thermal expansion of a photosensitive cylinder but flanges formed by using an ordinary inexpensive conductive resin material to be adhered and mounted not by a costly conductive adhesive but by an ordinary inexpensive adhesive which is a nonconductive adhesive in mounting the flanges formed by using the conductive resin material to the photosensitive cylinder. CONSTITUTION:This photosensitive drum is constituted by providing the adhesive groove parts L adjacently to the press-patching part K of the flange A 111 which is formed by using the conductive resin material and is to be pressfitted into the bore of the photosensitive cylinder 10 and sticking a nonconductive adhesive to the inlet part of the bore of the photosensitive cylinder 10, thereby press-fitting, adhering and mounting the flange A 111 formed by using the conductive resin material. The flange B 112 made of the conductive resin material with a gear having the same structure is mounted to the opposite side of the photosensitive cylinder 10. |
