Abstract
An image forming apparatus, including: a rotatable image bearing member; a developing unit configured to supply a developer onto the image bearing member; a transfer unit configured to transfer the developer on the image bearing member to a recording medium by a transfer voltage being applied to the transfer unit by a voltage applying unit; and a cleaning unit configured to remove the developer on the image bearing member, wherein when the apparatus stops an image forming operation halfway, the apparatus executes a recovery operation in which the image bearing member is rotated while the voltage applying unit applies a voltage to the transfer unit so that a part of the developer remaining on the image bearing member is once transferred from the image bearing member to the transfer unit, transferred again from the transfer unit to the image bearing member, and then removed by the cleaning unit.
