Abstract
An image forming apparatus includes a main control unit including a plurality of control units, and a sub control unit configured to respond to a request from an information processing apparatus via a network in substitution for the main control unit when the main control unit is being operated in a power saving state, wherein, in a case where the sub control unit receives a request to which the sub control unit cannot perform proxy response from the information processing apparatus, the main control unit determines a number of the control units for responding to the request among the plurality of control units and returns from the power saving state to a normal state using the control units the number of which is determined.
