<p>A fixing unit is used for fixing an toner image on a recording medium onto the recording medium. The fixing unit includes a heater which generates heat when supplied with an electric current. A control circuit selectively output a signal so as to turning ON and OFF a transistor. When the transistor is ON, the electric current is supplied to the heater. The signal output from the control circuit includes a pulse portion having pulses and a continues portion having no pulse. When the pulse portion is output, the electric current to the heater is intermittently disrupted. Because, a rush current generated in the electric current is also intermittently disrupted accordingly, flicker in lightning which is sharing a power source with the fixing unit can be prevented. <IMAGE></p> |
