1. An image forming apparatus, comprising:
a forming component configured to form an image;
a storage component configured to store 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 component;
a correction component configured to correct a density of the image formed by the forming component for each of the plurality of regions based on the correction data stored in the storage component;
a measurement component configured to measure an image formation density by the forming component in association with the correction by the correction component; and
a changing component configured to change 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 component approaches a predetermined target density.
