Abstract
A support shaft supporting a photosensitive drum detachable in the radial direction is supported by a bearing. This bearing is pressed and fixed by a specified device disposed at a specified position along the outer circumference of the photosensitive drum, and this device can be displaced from the specified position. A joint integrally rotatably linked to the support shaft and the photosensitive drum drive shaft is disposed so as to be able to be disconnected from either of the support shaft or the photosensitive drum drive shaft. This joint is engaged with a joint operating means for operating the joint. This joint operating means interlocks the placing action of the above device with the connecting action of the joint, and interlocks the displacing action of the device with the disconnecting action of the joint. Simultaneously with attaching/detaching of the device, the support shaft of the photosensitive drum and the photosensitive drum drive shaft are connected or disconnected.
