Abstract
An image forming apparatus includes a first detector detecting an operation sound based on a sound wave received by a receiver; a second detector detecting basis weight of recording material based on an ultrasonic wave transmitted from a transmitter and received by the receiver; a switching unit that switches destination of a reception signal from the receiver between a first path to the first detector and a second path to the second detector; and a controller that controls the switching unit such that the reception signal is output to the first path at a first timing and to the second path at a second timing. When a predetermined condition is satisfied, the controller controls the switching unit such that the reception signal is output to the second path at the first timing or to the first path at the second timing.
