A photosensitive drum, for use with an image forming apparatus, includes a cylinder, which has a photosensitive layer at its surface, to which a processing unit is contacted, and a flange provided at its longitudinal end portion. The flange includes a portion to be supported inside the cylinder by a supporting shaft supporting the photosensitive drum, and a supporting portion for supporting an inner peripheral portion of the cylinder in a contact area in which the processing unit contacts the cylinder. The supporting portion is placed in a state in which the supporting portion supports the inner peripheral portion of the cylinder by supporting the photosensitive drum by the supporting shaft. |
