An image forming apparatus is disclosed that can specify the cause and the part of an electrical failure with an inexpensive configuration and facilitate the maintenance by a user or an administrator. Power is supplied to function units in the image forming apparatus and a value is detected by a power detection unit. A state of the image forming apparatus is specified by a first control unit that can determine, based on the specified state and the detected value, whether or not there is an electrical failure. If there is a determined electrical failure, the power is supplied separately to the function units so that the first control unit can specify an electrically failed part based on a state of the image forming apparatus estimated at the separate supply and the detected value, and can notify a user or an administrator of the specified failed part.
