Title: Image forming apparatus that may correct the positional alignment of images

Abstract: An image forming apparatus includes: plural image holding members, on respective surfaces of which toner images are formed, the toner images being arrayable such that the length in the array direction and the color are different between adjacent toner images; a transfer body, onto which the toner images formed on the plural image holding members are transferred, such that there is a spacing between the adjacent toner images in the array direction; a detecting unit, detecting the length in the array direction of each of the toner images transferred onto the transfer body and detecting the amount of shift in the array direction of each toner image from a reference position; and a correction unit, correcting misalignment of each toner image of each color using the shift amount of the toner image with a length detected by the detecting unit within a predetermined threshold range.
