Abstract:
An image forming apparatus containing a fusing device, a commercial power source providing power to the fusing device, a triac, a thermistor detecting a temperature of the fusing device, a fusion control unit controlling the fusing device based on a detection result of the thermistor, and a cathode terminal outputting a control current and an anode terminal receiving the control current to control the power supplied to the heating body from the commercial power source and the triac. The fusion control unit of the image forming apparatus contains a control current output terminal outputting the control current to the anode terminal, a control current input terminal receiving the control current from the cathode terminal, and a fusion temperature control unit controlling the control current received by the control current input terminal and the control current output by the control current output terminal.
