The image carrier supporter temporarily fixes an image carrier inside a process cartridge of an image forming apparatus. The image carrier supporter includes a penetration shaft, and first and second fixing members. The penetration shaft includes first and second ends, and penetrates through a center throughhole of the image carrier. The first and second fixing members are provided at the first and second ends, respectively, of the penetration shaft, and are configured to closely contact a circumferential inner surface of the image carrier and a frame of a process cartridge, respectively. The process cartridge is configured to be attachable to and detachable from the image forming apparatus, and includes a frame, the image carrier, the image carrier supporter, and a process mechanism configured to form an image on the image carrier.
