Abstract
An image forming apparatus includes a control unit configured to perform a rubbing mode in which a rubbing rotatable member moves from a separation position to an abutment position in a state where a fixing belt is in a stop state. The control unit is configured to control a contact-and-separation mechanism in the rubbing mode such that if a predetermined temperature to which the fixing belt is heated is a first temperature, the rubbing rotatable member moves from the abutment position to the separation position at a timing when a first time has elapsed since the rubbing rotatable member abutted against the surface of the fixing belt, and if the predetermined temperature is a second temperature higher than the first temperature, the rubbing rotatable member moves from the abutment position to the separation position at a timing when a second time shorter than the first time has elapsed.
