Abstract: An image forming apparatus includes a phase controller for controlling input power applied to a heating body through phase control. The image forming apparatus includes a fuser having the heating body, a switching unit supplying the input power to the heating body, and a phase controller determining an input phase of the input power based on a temperature of the fuser, in which the phase controller further controls the switching unit to vary a phase of the input power supplied to the heating body within a phase range set based on the input phase, for each control cycle of the input power.
