To provide a photoreceptive drum whose frictional sound by rotation is comparatively small by enhancing the reliability of continuity with time between the inner peripheral surface of a drum part and the main body of an image forming apparatus, a process cartridge and the image forming apparatus.

The photoreceptive drum 1 is provided with the drum part 2 and a bearing part 5 installed at the inside of the drum part 2 and engaged with a shaft member 10 inserted from the outside of the drum part 2. Then, the inner peripheral surface 2a of the drum part 2 is electrically connected with a conductive member 12 installed at the outside of the drum part 2 by interposing the bearing part 5 and the shaft member 10 by the engagement of the bearing part 5 with the shaft member 10.
