Abstract

See full text

In an image forming apparatus, a communication device is selectively operable in a communication device side normal mode and a sleep mode consuming less power than the communication device side normal mode. The controller is selectively operable in a controller side normal mode, a first sleep mode consuming less power than the controller side normal mode, and a second sleep mode consuming less power than the first sleep mode. The controller is configured to: transmit to the communication device a command instructing to transit to the sleep mode in response to transition to the second sleep mode; maintain the sleep mode regardless of return from the second sleep mode to the first sleep mode; and transmit to the communication device a command instructing to return from the sleep mode to the communication device side normal mode in response to return to the controller side normal mode.
