Abstract
An image forming apparatus receives light from an intermediate transfer member or a correction pattern. The pattern includes an overlapping pattern on which a first monochromatic toner image is formed as a lower layer and a second monochromatic toner image having a smaller area than the first monochromatic toner image is formed as an upper layer. The image forming apparatus controls a plurality of image forming units to form the overlapping pattern such that a dynamic range becomes less than 1.0 and greater than 0.5.
