Abstract
An image forming apparatus having two or more different rated voltages, the image forming apparatus including a voltage detecting unit, which detects a voltage level of alternating current (AC) power supplied from outside of the image forming apparatus; a control unit, which outputs a control signal according to the detected voltage level; a fusion driving circuit, which controls a number of waveforms and phase of the AC power according to the control signal and outputs the controlled AC power as fusing power; and a fuser including a heat generating body having a negative temperature coefficient (NTC) characteristic, which receives the fusing power and generates resistance heat; and a heating member, which is heated by the heat generated by the resistance heat generating body and fuses an image formed on a printing medium.
