Patent ID: 8274176

Claim:
A power supply apparatus comprising: a high voltage generating unit, which generates one or more output voltages by using an input voltage, and which is implemented as a chip; and one or more output terminals formed on a same circuit board as the high voltage generating unit, to output the generated one or more output voltages, wherein the chip comprises: a transforming unit to transform the input voltage into one or more transformed voltages that are different from one another; and a rectifying unit to rectify the transformed voltages into rectified voltages, and to determine the rectified voltages as the generated one or more output voltages, wherein the one or more output terminals are installed in an image forming apparatus, and each of the output terminals is connected to at least one of a plurality of electronic components of the image forming apparatus directly or through an electric wire, and wherein the plurality of electronic components include a charging unit, an exposure unit, a developing unit, a transferring unit, a fixing unit and a cleaning unit.
