Abstract
An image forming apparatus includes a first communication processing unit and a second communication processing unit, which communicate with an external device, respectively. A power supply unit supplies power to the second communication processing unit and a switching unit switches from the first communication processing unit to the second communication processing unit as a communication destination of the external device, when the first communication processing unit receives data from the external device in a power-saving state where the power supply unit supplies power to the first communication processing unit and the power supply unit stops supplying the power to the second communication processing unit.
