Abstract:
1. An image forming apparatus comprising: an image bearing member on which a toner image is formed; a rotatable intermediate transfer member having an elastic layer, to which the toner image on the image bearing member is transferred at a primary transfer nip; a transfer member configured to come into contact with the intermediate transfer member so as to form a secondary transfer nip, and transfer the toner image on the intermediate transfer member to a recording material at the secondary transfer nip; a conveying device configured to convey the recording material to the secondary transfer nip; a cleaning member configured to be in contact with the intermediate transfer member and clean the intermediate transfer member; a detection device configured to detect the recording material on a pass of the secondary transfer nip; a driving member configured to drive the intermediate transfer member; and a controller configured to, decide according to the output of the detection device whether the recording material exists or not at the secondary transfer nip when the recording material stops in the image forming apparatus during an image forming operation, and in a recovery operation, drive the driving member after the stopped recording material has been removed such that a driving time of the driving member is longer in a case that the controller decides that the recording material existed at the secondary transfer nip than in a case that the controller decides that the recording material did not exist at the secondary transfer nip.
