Abstract:
In an image forming apparatus, when no image is being formed, an image bearing member is rotated at least one rotation, in a state in which a transfer bias is controlled such that a potential on a surface of the image bearing member on the upstream side in the rotational direction of a cleaning apparatus is a polarity opposite to that of a developer.
