Abstract
Provided is an image forming apparatus, which is capable of detecting a color misregistration amount with high accuracy even when a density characteristic thereof is changed. The image forming apparatus includes a plurality of image forming units configured to form toner images of different colors on a predetermined intermediate transfer belt, and a density sensor configured to measure densities of the toner images formed on the intermediate transfer belt. The image forming apparatus determines a density target depending on a measurement result of a density correction image, which is formed by the plurality of image forming units, from the density sensor. The image forming apparatus causes the plurality of image forming units to form position detection images so that the position detection images have densities corresponding to the density target.
