| 1. A fusing apparatus for fusing toner onto paper, comprising:
a fusing unit which is resistance-heated or induction-heated by an induced current and fuses toner onto paper using heat;
a sensing unit for sensing fusing unit temperature;
an ON/OFF signal generation unit for generating an ON/OFF signal for turning the fusing unit ON or OFF according to the fusing
unit temperature; and
a pulse width modulation (PWM) signal generation unit for generating a PWM signal in response to the ON signal so that the
amount of induced current input to the fusing unit gradually increases relative to a reference current.
