Abstract
When an operation mode of an image forming apparatus returns from an energy-saving mode to a regular operation mode, a CPU of a main system outputs a power control signal set to High, and determines the necessariness of information display on an LCD of an operation unit control system to output a starting mode selection signal set to High when the result of the determination is positive. A CPU of the operation unit control system detects the state of a power control signal, and detects mode return from the energy-saving mode depending on the result of the above detection. The CPU of the operation unit control system also detects the state of a starting mode selection signal, and determines the necessariness of information display on the LCD depending on the result of the detection to carry out a display process depending on the result of the determination.
