An image processing apparatus includes a network control unit, a main control unit, a clock circuit unit, a sub control unit, and a power mode switching unit. The main control unit transmits transition information to the sub control unit during a transition to a first power saving mode when power supply to the main control unit is stopped. The clock circuit unit transmits a transition instruction to the sub control unit at a specified time. When detecting the transition instruction during the first power saving mode, the sub control unit selectively controls the power mode switching unit to switch a power mode based on the transition information between transition from the first power saving mode to the normal mode and transition from the first power saving mode to the second power saving mode when power supply to the main control unit and the network control unit is stopped.
