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 48):
The image forming apparatus according to  claim 45 , wherein\n the image formation unit further forms, on the surface of the image carrier, a third patch image that passes through the first region, and a fourth patch image of a color that is the same as that of the third patch image and that passes through the second region, so as to be located at the same position in the movement direction, the control unit further detects, as a positional misregistration amount between the first light receiving element and the second light receiving element, a difference between a position of the third patch image and a position of the fourth patch image, based on signals respectively outputted from the first light receiving element and the second light receiving element when the third patch image and the fourth patch image pass through the first region and the second region, respectively, and the control unit performs the color misregistration correction control based on the detected color misregistration amount and the positional misregistration amount.
