Image forming apparatus capable of changing the number of light receiving elements of a light receiving unit
An image forming apparatus includes an image carrier, an image forming unit configured to form a patch image on the image carrier, and a light emitting unit. In addition, a light receiving unit receives light reflected by the patch image when the patch image that moves with movement of the image carrier is irradiated with light by the light emitting unit, and includes one or more light receiving elements. A setting unit sets a first subset of light receiving elements for receiving reflected light from a first patch image and sets a second subset of light receiving elements for receiving reflected light from a second patch image, with the number of light receiving elements in the first subset differing from that in the second subset.
