PROBLEM TO BE SOLVED: To obtain a high quality picture by accurately and securely mounting a flange on both ends of a cylindrical body of a-Si photoreceptor and by preventing runout from generating in the cylindrical body when the flange-mounted photoreceptor is subsequently attached to an electrophotographic device and rotated. SOLUTION: The photoreceptor is obtained by installing an inlay section 7, with the inside diameter larger than the center of the cylindrical body 2, on the inner surface at both ends of the cylindrical body 2 which is made of aluminum and formed with an amorphous silicon photosensitive layer 1 on the outer circumference. In this photoreceptor, the inside diameter of the inlay section 7 is set narrowingly toward the outermost end of the cylindrical body 2. In addition, the inside diameter A of the inlay section 7 in the outermost end and the outside diameter B of a disk-like flange 8 to be inserted into the inlay section 7 are set so as to satisfy the relation of 0≤B-A≤0.12 mm.
