Abstract
An image processing apparatus includes: a first controller including first control circuitry and first power supply control circuitry; and a second controller including second control circuitry and second power supply control circuitry. The first control circuitry controls an image former. The second control circuitry controls an external interface. In a case where power supply to the first control circuitry and the second control circuitry except for general-purpose input-and-output ports is stopped in a power saving mode, when detecting a factor of recovery from the saving mode, the second power supply control circuitry powers on the second control circuitry though a general-purpose input-and-output port and notifies the first power supply control circuitry of the recovery though a general-purpose input-and-output port, and when receiving notification of the recovery from the second power supply control circuitry, the first power supply control circuitry powers on the first control circuitry though a general-purpose input-and-output port.
