DRIVING DEVICE OF ROTATIONAL BODY FOR USE IN IMAGE FORMING APPARATUS

摘要

A driving device for a rotational photoreceptor drum for use in an image forming machine, in which a rotational drive from a motor is supplied through a gear train to the axial shaft of the drum. The shaft is connected to the drum only at the side farthest from the gear train. An inertia member is provided within the drum. A rotational member having a rotational resistance is brought in contact with a non-image region of the drum.
