Abstract
To control a temperature of a rotating member for fixing an image during standby, an image forming device can suppress overshoot of the temperature of the rotating member occurred when a fixing state is switched to a standby state. Determining the standby temperature is higher than the fixing temperature (Step S: YES), a CPUcontrols a temperature of a heating rollerto be kept substantially at a first temperature (Step S). After a lapse of first given time (Step S: YES), the CPUstops rotation of the heating roller, a fixing rollerand the pressure roller(Step S). The CPUcontrols the temperature to be kept substantially at the second temperature (Step S). After a lapse of second given time (Step S: YES), the CPUcontrols the temperature to be kept substantially at the standby temperature, and switches to the standby state.
