PURPOSE: To facilitate holding and handling of a photosensitive drum with a simple constitution and to prevent an erroneous setting by providing the nonrotating member of the photosensitive drum with a hook.

CONSTITUTION: The hook 6 is fixed on the end of a fixed spindle extend at both sides through the center of the photosensitive drum main body 2. When the photosensitive drum 1 is loaded on a device, the fixed spindles fall into the drum grooves 8 and 8' of a kid frame 7. At this time the drum can be held and handled far easily by grasping the hook 6. Even if the drum is set upside down in order to load it, the erroneous setting can be prevented, because the hook 6 works together with the groove 8' to prevent the drum from falling.
