Abstract:
An image forming apparatus has a normal mode and a power saving mode. The image forming apparatus includes a printing portion for performing printing, a communication portion for performing a communication process, a system controller for performing operation control of the apparatus and a process concerning communication, and a power supply controller configured to supply power to the printing portion, the system controller, and the communication portion in the normal mode while in the power saving mode, to supply power to the communication portion but to stop power supply to the printing portion. The system controller performs the process concerning communication during the power saving mode, and the power supply controller adjusts a length of a stop time so that average power consumption of the image forming apparatus does not exceed a permissible maximum power, so as to temporarily restore the system controller during the power saving mode.
