PROBLEM TO BE SOLVED: To provide a drum flange which effectively suppresses bulging of each end of a drum by pawls of a metal plate for rotation stop by a very simple mechanism without enlarging a photoreceptor drum or increasing the apparatus cost. SOLUTION: The drum flange fastened to each end of a hollow cylindrical photoreceptor drum 50 consists of a resinous flange main body 1 comprising a flange board 1a and a flat columnar part 1b formed on one face of the flange board, and a metal plate 2 for rotation stop fixed on the flat columnar part of the resinous flange main body. The metal plate for rotation stop consists of a discoid substrate part having a smaller diameter than the flange board of the resinous flange main body, and a plurality of pawls 12 formed on the peripheral edge of the substrate part. The pawls have an inclined part, at least the tip of which protrudes from the peripheral edge of the flange board of the resinous flange main body 1, wherein the inclined part inclines toward the resinous flange side.
