Zusammenfassung:An image forming apparatus includes a heater, a first heater drive circuit which rectifies AC power from an AC power supply and subjects a current to be conducted to the heater to PWM control, and a second heater drive circuit which allows conduction from the AC power to the heater. The image forming apparatus further includes a switching circuit which sets a drive circuit which is to drive the heater to any one of the first heater drive circuit and the second heater drive circuit and a control unit which controls switching between the drive circuits by the switching circuit.
