Abstract
An image forming apparatus includes a fixing member that fixes, onto a recording material, a toner image that has been transferred onto the recording material, a recovery roller that recovers toner adhering onto the fixing member, a cleaning unit, and a controller. The cleaning unit includes a cleaning web that cleans the recovery roller, a first roller around which the cleaning web is wound in advance, a second roller that winds the cleaning web supplied from the first roller, and a third roller that presses the cleaning web against the recovery roller to clean the recovery roller. The controller stops a rotation of a rotor of a motor that drives the second roller, in a case where a value corresponding to a torque applied to the rotor exceeds a threshold while the rotor is rotating.
