PURPOSE:To make a photoreceptor drum small by shortening the length of a part which does not contribute to forming an image and also to miniaturize a device main body and to reduce the cost in an electrophotographic device. CONSTITUTION:The photoreceptor drum 30 is constituted of a photoreceptor cylinder 31 and flanges 32 and 32 provided at both ends of the cylinder 31. The photoreceptor cylinder 31 is constituted of a cylindrical photoreceptor base substance 35, and a photoreceptive layer 36 provided in uniform thickness on the outer periphery of the base substance 35. The outside diameter of both ends 35a and 35a of the base substance 35 is formed to be smaller and smaller toward an outer side in an axial direction. The outside diameter of the cylinder 31 is made equal over the entire length thereof by press-fitting the small- diameter part 32b of the flanges 32 and 32 in both ends of the cylinder 31 toward an inner side from the outside in the axial direction. |
