Abstract
An image forming apparatus includes an operating key, an illuminance sensor, and a controller. The operating key contains a lamp. The illuminance sensor detects an ambient illuminance. The controller controls turning on and off of the lamp. The operating key functions as a first trigger for return from a power-saving mode to a normal mode. The controller turns the lamp off when the ambient illuminance detected by the illuminance sensor in the power-saving mode is equal to or more than a first threshold value, and the controller turns the lamp on when the ambient illuminance detected by the illuminance sensor in the power-saving mode is less than the first threshold value.
Claims4
An image forming apparatus comprising:
- an operating key containing a lamp;
- an illuminance sensor that detects an ambient illuminance;
- and
- a controller that includes a processor and controls, through the processor executing a control program, turning on and off of the lamp,
- wherein the operating key functions as a first trigger for return from a power-saving mode, where power consumption is reduced relative to a normal mode, to the normal mode, and
- the controller turns the lamp off when the ambient illuminance detected by the illuminance sensor in the power-saving mode is equal to or more than a first threshold value, and the controller turns the lamp on when the ambient illuminance detected by the illuminance sensor in the power-saving mode is less than the first threshold value.
