Abstract: A toner detection unit is configured by an LED that irradiates light toward an intermediate transfer belt, first and second light receiving elements that respectively receive specular reflection light and diffused reflection light of light irradiated toward the intermediate transfer belt from the LED, a circuit board, and a housing. The LED and the light receiving elements are mounted in a line on the circuit board. The housing is configured to guide, to the first light receiving element, the specular reflection light from a first region within an irradiation region on which light is irradiated from the LED on the intermediate transfer belt, and to guide, to the second light receiving element, the diffused reflection light from a second region which is different from the first region within the irradiation region.

Abstract: A toner detection unit includes an LED and a light receiving element that outputs a current in accordance with a received light amount. A current/voltage converter circuit converts the current outputted from the light receiving element into a voltage and outputs the voltage. A voltage amplifier circuit for amplifies a difference between the voltage outputted from the converter circuit and a reference voltage and outputs the amplified difference as a voltage corresponding to the received light amount. A microcomputer measures the voltage outputted from the voltage amplifier circuit by causing the LED to emit light, under a measurement condition under which the reflected light is not incident on the light receiving element through an opening formed in a housing of the toner detection unit, and adjusts the reference voltage used in the voltage amplifier circuit based on the obtained measured voltage.
