<P>PROBLEM TO BE SOLVED: To provide a rotating body driving device which achieves high image quality by reducing a speed variation component generated in a driving transmission system, and improves the stripe of an image caused by density unevenness called banding, and also to provide a photoreceptor unit equipped with the rotating body driving device, and an image forming apparatus equipped with the photoreceptor unit. <P>SOLUTION: The rotating body driving device has: a photoreceptor; a photoreceptor shaft attached to the photoreceptor; a driving motor for driving the photoreceptor; a driving motor shaft attached to the driving motor; a first gear attached to the driving motor shaft; and a driving transmission gear for transmitting the driving of the driving motor from the first gear to the photoreceptor shaft, and rotates the photoreceptor. An inertia body is provided on the same shaft of the driving motor. <P>COPYRIGHT: (C)2008,JPO&INPIT |
