Abstract
An image forming apparatus includes a forming unit, a generation unit, a storage unit, a correction unit, and a changing unit. The forming unit forms an image. The generation unit generates correction data for correcting density unevenness for each of a plurality of regions divided in a main scanning direction of an image formed by the forming unit. The storage unit stores the correction data generated by the generation unit. The correction unit corrects a density of an image to be formed by the forming unit for each of the plurality of regions based on the correction data stored by the storage unit. The changing unit changes an image formation density by the forming unit with a uniform amount of change for the plurality of regions after the correction data is generated by the generation unit.
