PROBLEM TO BE SOLVED: To surely absorb vibration occurring when rotating a photoreceptor drum and to enhance the adhesion of vibration-proof material to the photoreceptor drum. SOLUTION: In this photoreceptor drum incorporated in the process cartridge of an image forming device, the vibration-proof material 1 equipped with a cylindrical member 4 made of metal, elastic material 3 surrounding at least one part of the outer surface of the member 4 and a coating layer 2 bringing the material 3 into contact with the outer surface of the member 4 is arranged inside a drum cylinder 5, so that the vibration of the photoreceptor drum is absorbed. |
