    • An image forming apparatus includes a fuser that fuses a paper medium and a fuser control device that controls an AC power supplied to the fuser. The fuser control device includes a phase detecting device that receives an AC voltage, detects zero-crossing points of the AC voltage, outputs a phase detecting signal when the zero-crossing points are detected, and selectively cuts off a flow of AC power into the phase detecting device in response to a mode control signal, a signal generator that generates a phase control signal to control a phase of the AC power supplied to the fuser based on the phase detecting signal, and a temperature controller that controls a temperature of the fuser by controlling the phase of the AC power supplied to the fuser according to the phase control signal.
