Patent ID: 8064786

Claim:
An image forming apparatus comprising: an image bearing member; an intermediate transfer member configured to bear a toner image transferred from the image bearing member; a primary transfer member configured to primary-transfer the toner image on the image bearing member to the intermediate transfer member; a first voltage application unit configured to apply to the primary transfer member a predetermined voltage of a first polarity for transferring the toner image on the image bearing member to the intermediate transfer member; a secondary transfer member configured to transfer the toner image on the intermediate transfer member to a recording material; a second voltage application unit configured to apply to the secondary transfer member a predetermined voltage of a second polarity for transferring the toner image on the intermediate transfer material to the recording material; an execution unit configured to execute a first discharging process of electrically discharging the intermediate transfer member by applying the voltage of the first polarity from the first voltage application unit to the primary transfer member, and a second discharging process of electrically discharging the intermediate transfer member by applying the voltage of the second polarity from the second voltage application unit to the secondary transfer member; and a selection unit configured to select a discharging process according to a charged state of the intermediate transfer member after secondary transfer.
