Abstract
An image forming apparatus includes a fixing device. The fixing device includes a fixing roller and a pressure roller. The fixing roller applies heat of a predetermined fixing temperature T1 to a print sheet S to which a toner image has been transferred. The pressure roller has a larger heat capacity than the fixing roller. A control portion of the image forming apparatus determines, in a power saving mode, whether or not a detection result of a temperature sensor is equal to or lower than a motor rotation start temperature T3 which is lower than the fixing temperature T1 (first step). Upon determining that the detection result is equal to or lower than the motor rotation start temperature T3, the control portion controls a driving motor to rotate the fixing roller at least once in the state where a halogen lamp has been lighted off (second step).
