Abstract
An apparatus for and a method of controlling a high voltage in an image forming apparatus using the high voltage with a high alternating current voltage superimposed on a high direct current voltage. The apparatus includes: a high alternating current voltage output unit outputting the high alternating current voltage; a high direct current voltage output unit outputting the high direct current voltage; and a controlling unit controlling the high alternating current voltage output unit and the high direct current voltage output unit such that the high alternating current voltage is output before the high direct current voltage when the high voltage is required for printing.
