ABSTRACT:
An image forming apparatus changes over an electric potential on an image bearing member in response to an attenuation region in which a remaining potential on an image bearing member attenuates after a developing bias applied to the developing member has been turned off after completion of an image forming operation. Accordingly, it is possible to mitigate adherence of developer due to a large potential difference between the developing member and the image bearing member.
