Abstract
An image forming apparatus includes an image forming device to form an image on an image bearer and circuitry configured to accept, from a user, an input of a density level selected from a plurality of different density levels and control an image forming condition under which the image forming device forms the image. The circuitry is configured to correct density unevenness of the image formed on the image bearer by the image forming device and correct the density unevenness of the image at the density level accepted. The density unevenness is unevenness appearing in a main scanning direction orthogonal to a direction of conveyance of the image bearer during image formation.
