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 51):
An image forming apparatus, comprising:\n an optical sensor; and an image formation unit, wherein the optical sensor comprises 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 in an irradiation region of the irradiated member, and a second light receiving element for receiving specular reflection light into which the irradiating light is specularly reflected in the irradiation region of the irradiated member, wherein the first light receiving element receives the diffused reflection light diffusely reflected in a first region within the irradiation region, and the second light receiving element receives the specular reflection light specularly reflected in a second region within the irradiation region, at least a part of which does not include the first region in a main scanning direction, and wherein the image formation unit forms, on a surface of the irradiated member, a first patch image that passes through the first region and a second patch image that passes through the second region.
