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 44):
An image forming apparatus, comprising:\n an image carrier that is rotated; the optical sensor according to  claim 31 , wherein the optical sensor is arranged at a position facing a surface of the image carrier and irradiates light toward the image carrier from the light emitting element; and a control unit configured to, based on a signal outputted from the first light receiving element or the second light receiving element when an image formed on the image carrier passes through a first region or a second region within an irradiation region, detect a position or a density of the image, and execute a color misregistration correction control based on the detected position of the image or execute an image density control based on the detected density of the image.
