PURPOSE:To reduce the size of a copying machine by mounting a drive motor in the drum of the copying machine using a photosensitive drum. CONSTITUTION:Three rollers 14, 14' and 14'' rotatably support together a photosensitive drum 15, in which a drive motor 16 is mounted. This motor 16 is fixed to a main side plate 12 and has its output shaft 16', to which a sprocket 17 is attached. The rotational force of the motor 16 is transmitted from the sproket 17 to a sprocket 19 so that the drum gear 22 fixed to the drum is turned through a shaft 20 and a gear 21. As a result, the drum 15 is turned without fail by the action of the motor 16. |
