Abstract
An image forming apparatus includes a forming unit, a storage unit, a correction unit, a measurement unit, and a changing unit. The forming unit forms an image. The storage unit stores correction data for correcting density irregularity in each of a plurality of regions obtained through division in a main scanning direction of the image formed by the forming unit. The correction unit corrects a density of the image formed by the forming unit for each of the plurality of regions based on the correction data stored in the storage unit. The measurement unit measures an image formation density by the forming unit in association with the correction by the correction unit. The changing unit changes the image formation density by the forming unit with a uniform change amount in the plurality of regions so that the image formation density measured by the measurement unit approaches a predetermined target density.
