PROBLEM TO BE SOLVED: To easily maintain assembling precision of a flange body to a drum body over a long period of time. SOLUTION: Regarding the drum flange mounting structure of the photoreceptor drum, the drum flange 2 mounted on one end of the drum body 1 includes: the flange body 5 assembled to the end portion of the drum body; and a rotation-stop metallic plate 6 assembled to a portion facing the inside of the drum body, of the flange body so that it can not relatively rotate. A plurality of pawls 12 are integrally formed on the outer peripheral part of the metallic plate for rotation stop at intervals in the peripheral direction, the plurality of pawls 12 are brought into pressure-contact with the inner surface of the drum body, and the flange body is assembled to the photoreceptor drum so that it can not relatively rotate to the drum body via the metallic plate for rotation stop. The metallic plate for rotation stop having the plurality of pawls that are brought into pressure-contact with the inner surface of the drum body is elastically displaced toward the flange body, thus, energizing force in a direction to pull the flange body into the inside of the drum body is applied.
