Image forming apparatus and image processing apparatus

An image processing apparatus supplying output image data for forming an image to an image forming apparatus having a photosensitive member, and an exposing unit configured to expose the photosensitive member with light to form an electrostatic latent image, the image processing apparatus comprising:

• an identifying unit configured to identify, on basis of image data, a pixel to be corrected among a plurality of pixels of an image to be formed from the image data;
• a holding unit configured to hold a plurality of correction information pieces describing correction amounts for an exposure amount;
• a correcting unit configured to select a correction information piece from the plurality of correction information pieces on basis of each distances between the pixel to be corrected and a plurality of edges of the image formed from the image data and to correct an exposure amount to be applied by the exposing unit to the pixel to be corrected on basis of the selected correction information piece from the exposure amount described in the image data to generate the output image data;
• and
• an output unit configured to output the output image data to the image forming apparatus.
