Abstract
A signal generation portion of an image forming apparatus generates a different level of signal according to an output value of a pyroelectric sensor. A recognition portion determines a measurement value on the speed of change of the signal and recognizes which of a first range and a second range the measurement value is. In a power supply portion, when the measurement value falls within the first range in a mode other than a power-saving mode, and the image forming apparatus is brought into the power-saving mode, and, when the measurement value falls within the second range in the power-saving mode, the power-saving mode is cancelled.
