Abstract
An image-forming apparatus includes: a forming unit that forms an image on an image holder that is a rotating body holding an image; a measuring unit that measures a rotation amount of the image holder with reference to a certain position on the image holder; a determining unit that: identifies a position on the image holder from which an image is to be formed by the forming unit, according to the rotation amount measured by the measuring unit; if, while a plurality of images are successively formed on the image holder, an image for density correction is to be formed, postpones forming of the image for density correction until a timing arrives at which one image of the plurality of images is to be formed from a predetermined position on the image holder, and when the timing arrives at which the one image of the plurality of images is to be formed from the predetermined position on the image holder, determines to start forming of the image for density correction from the predetermined position, instead of forming the one image of the plurality of images; and a correction unit that obtains a reading result of the image for density correction formed by the forming unit from the predetermined position, and corrects a density of at least one of the plurality of images on the basis of the obtained reading result.
