Further, by being pulled out of the copying machine main body 12), the cleaning device 09 does not disengage from the protrusion or guide (25), and also prevents the cleaning device 09 from disengaging from the developing device (8) and the transfer charger (p etc. is the copy machine body (2)
Since it is fixed inside, it is rotatable about the joint shaft (45) as a fulcrum. Therefore, as shown in FIGS. 4(b) and 5, by rotating the cleaning device (19) below the photosensitive drum (1) and turning on the serviceman switch, the motor (41) is activated. It is activated to rotate the support shaft and the joint shaft (the photoreceptor drum as well as the center), and in this state, the surface of the photoreceptor drum (1) is cleaned.

Since the cleaning device (19) can be attached to the lower part of the photoreceptor drum (1), the drum surface can be cleaned without separating the cleaning device (19) from the photoreceptor drum (1). Moreover, the photosensitive drum 1
When the photoreceptor drum (1) is removed from the copying machine main body (2), the cleaning device 119) functions as a stand for the photoreceptor drum (1), and the risk of damaging the drum surface is largely eliminated. The cleaning device (mQ9) is used as a stand, and when replacing the photoreceptor drum (), the opening on the cleaning device side faces upward, so toner will not spill out. It becomes unnecessary.
