ABSTRACT:
An image forming apparatus includes a fixing device for fixing developer on a recording medium; a heating device for heating the fixing device; a cooling device for cooling the fixing device; a temperature detecting device for detecting a temperature of the fixing device; a heating device control unit for controlling drive of the heating device; and a cooling device control unit for controlling drive of the cooling device. After the fixing device fixes the developer on the recording medium, when the temperature detecting device detects the temperature of the fixing device below a first temperature, the cooling device control unit reduces cooling effect of the cooling device.
