Abstract:
An image forming apparatus includes: specifying unit configured to specify, based on image data, a pixel to be subjected to correction from among pixels of an image to be formed from the image data; and a correction unit configured to correct an exposure amount of an exposure unit for the pixel to be subjected to correction from an exposure amount indicated by the image data. The correction unit is further configured to correct the exposure amount applied by the exposure unit to the pixel to be subjected to correction by not exposing at least a portion of a region of the pixel to be subjected to correction according to the distance between the pixel to be subjected to correction and an edge of the image to be formed from the image data.
