An image forming apparatus includes a controller that provides control in which, if image formation processing by a single unit is executed first since a density adjustment condition for adjusting a density of an image is satisfied, a density adjustment value is changed by a predetermined basic change amount, and a first image is formed in a corresponding image formed region with a density that is adjusted in accordance with the changed density adjustment value, and control in which, if a single image other than the first image is formed in the corresponding image formed region, the current density adjustment value is changed by a predetermined fine change amount that is smaller than the basic change amount, and the single image is formed in the corresponding image formed region with a density that is adjusted in accordance with the changed density adjustment value.
