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.

Claim (Index 31):
An optical sensor, comprising:\n a light emitting element that irradiates irradiating light toward an irradiated member; a first light receiving element for receiving diffused reflection light into which the irradiating light is diffusely reflected by the irradiated member; a second light receiving element for receiving specular reflection light into which the irradiating light is specularly reflected by the irradiated member; and a housing for forming a first opening and a second opening, wherein the first opening is a common opening through which the irradiating light passes and through which the diffused reflection light to be received by the first light receiving element passes, and the second opening is an opening through which the specular reflection light to be received by the second light receiving element passes.
