Abstract
An image forming apparatus includes a fixing unit and a control unit. The fixing unit includes a rotating endless belt, a rotary member, a heating member, a driving unit, and a separation member arranged facing a circumference of the endless belt and configured to separate the recording material, after passing through the nip portion, from the endless belt. The control unit is configured to control the driving unit such that the endless belt stops along with an end of a fixing processing and rotates when a temperature of the endless belt passes a glass transition temperature of the endless belt from higher than the glass transition temperature of the endless belt to lower than the glass transition temperature of the endless belt.
