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.

Abstract: A housing includes a first opening and a second opening, and encloses a light-emitting element and a first light receiving unit. The first opening is provided in a first light guide path, and is arranged so that light output from the light-emitting element travels toward a target surface. The second opening is provided in a second light guide path arranged between the target surface and the first light receiving unit. The first opening is an exit opening of a through-hole provided penetrating through the housing, and a shape of the through-hole is a shape in which diffracted light of the +1st order and higher orders and diffracted light of the −1st order and higher orders produced at the target surface to be irradiated are not incident on the first light receiving unit.

Abstract: A housing includes a first opening and a second opening, and encloses a light-emitting element, a first light receiving unit, and a second light receiving unit. The first opening is provided in a first light guide path arranged between the light-emitting element and a first irradiated region of the target surface, and is arranged so that light output from the light-emitting element travels toward the first irradiated region. The second opening is provided in a second light guide path arranged between the first irradiated region and the first light receiving unit, and is arranged so that diffused reflection light from the toner image passes through when the toner image passes the first irradiated region.

Abstract: A recording material determination apparatus includes a transmission unit, a reception unit, and a determination unit. The transmission unit transmits an ultrasonic wave to a recording material. The reception unit vibrates when the reception unit receives the ultrasonic wave having been transmitted from the transmission unit and having passed through the recording material, and outputs a signal corresponding to a vibration state. The determination unit determines a basis weight of the recording material in accordance with the signal output from the reception unit. A resonance frequency of the reception unit differs from a resonance frequency of the transmission unit, and the reception unit is capable of receiving a sound wave in an ultrasonic range and a sound wave in an audible range.
