An image forming apparatus including plural image forming units each having an image-carrier includes: a cylindrical image-carrier body holding an image; a rotary shaft inserted in the image-carrier body, and rotatably supporting the image-carrier body; a coupling member fitted to an end portion of the rotary shaft, transmitting a rotational-drive-force to the rotary shaft; an engaging member projecting from a circumferential surface of the rotary shaft, being engaged to an engaged portion formed in the image-carrier body to disable relative rotation of the image-carrier body to the rotary shaft; and an attaching member continuously inserted into a first through hole formed in the coupling member and a second through hole formed in the rotary shaft and fixed thereto such that an angle formed between the engaging member and the attaching member is substantially 90 degrees as seen in an rotary shaft axial-direction, attaching the coupling member and the rotary shaft.
