PROBLEM TO BE SOLVED: To fit a flange to a photoreceptor drum by reducing the distortion of the photoreceptor drum or the flange without causing a grounding defect when the flange is fitted to the photoreceptor drum. SOLUTION: This electrophotographic photoreceptor flange 1 is used by being fitted to the aperture end of the electrophotographic photoreceptor drum having a photosensitive layer on the outside circumferential surface of a cylindrical conductive substrate. Then, the flange 1 is constituted so that a ring-like groove 2 is engraved at the outside circumference of the engagement part 4 thereof engaged with the inside circumferential surface of the electrophotographic photoreceptor drum and a ring-like elastic member 3 whose maximum outside circumferential diameter is set to be larger than the outside circumferential diameter of the engagement part 4 is fitted in the groove 2. |
