A fixing device includes a temperature detection unit that detects temperature associated with temperature of an abutting section of a fixing roller and a pressing roller, and a control unit that controls a driving motor based on detection temperature by the temperature detection unit. When the fixing device is activated, if it is determined that detection temperature by the temperature detection unit is not equal to or less than predetermined temperature, the control unit drives the driving motor at a setting speed set in advance, and if it is determined that the detection temperature is equal to or less than the predetermined temperature K, the control unit drives the driving motor at a predetermined low speed lower than the setting speed.
