Abstract
An image forming apparatus includes an image carrier, an exposure device, a developer image forming unit, a memory, and a processor. The image carrier carries a developer image. The exposure device exposes the image carrier. The developer image forming unit forms the developer image by transporting a developer to a latent image formed on the image carrier. The processor generates correction data for correcting density unevenness in a main scanning direction detected based on an image generated by the developer image, corrects the density unevenness in the main scanning direction occurring in the developer image by changing an exposure amount when the image carrier is exposed by the exposure device, using the generated correction data, and when a position change of the developer image forming unit in the main scanning direction is detected, adjusts the correction data by a detected position change amount.
