Abstract
An image forming apparatusis configured to detect a human present in a first range (detection area A) from the image forming apparatususing an ultrasonic wave that is output at a first frequency from an ultrasonic sensor. If a human is detected in the detection area A, the image forming apparatusswitches the frequency of the ultrasonic wave that is output from the ultrasonic sensorto a second frequency that is lower than the first frequency, and is controlled to detect the human in a second range (detection area A) that is smaller than the detection area A. When a human is detected in the detection area A, data communication is started using the ultrasonic wave output from the ultrasonic sensor
