Abstract
An image forming apparatus includes an image bearer, an image forming unit, a toner image detecting unit, and a detection processing unit. The image bearer is configured to bear a toner image. The image forming unit is configured to sequentially form groups of pattern images for a plurality of colors in a sub-scanning direction of the image bearer, each of the groups including pattern images of the same color at a predetermined interval. The toner image detecting unit is configured to detect the pattern images formed on the image bearer. The detection processing unit is configured to recognize whether an interval between adjacent pattern images of the same color corresponds to a set interval, to exclude an image for which the interval does not correspond to the set interval among the detected pattern images.
