Abstract
The present invention prevents a particular portion of a drum-like image bearing member from being physically damaged or chemically deteriorated by the image bearing member being reciprocally moved in the direction of the rotational axis thereof. For this purpose, the rotational movement of a rotary shaft driving the image bearing member is utilized to produce a force for moving the image bearing member in the direction of the rotational axis.
