Provided is an image forming apparatus and a method of controlling the same. When an external power is supplied to a heating resistance member of a fusing unit in the image forming apparatus that is in a standby mode, a power supply unit supplies an internal power to a different load (for example, an exposure unit, a developing unit, or a transfer unit) in one or more time sections so as to supply the internal power to the load at a continuously changing operating frequency.
