In a first power state of an image forming apparatus in which a first power supply unit supplies power to a network I/F but does not supply power to a central processing unit (CPU), if a received packet is a first type packet, a power supply control unit shifts the image forming apparatus to a second power state in which the first power supply unit supplies power to the CPU but the second power supply unit does not supply power to the image forming unit. If the received packet is a second type packet, the power supply control unit shifts the image forming apparatus to a third power state in which the first power supply unit supplies power to the CPU and the second power supply unit supplies power to the image forming unit. |
