摘要： An image forming apparatus includes an image processing unit that has line heads that include a plurality of light sources disposed in a line shape in a main scanning direction, causes each light source to emit light onto image data to form pixels on an exposed surface, and performs image exposure, and creates two-dimensional image data to be printed on the basis of an image signal from the outside and an operation instruction. The image processing unit corrects the two-dimensional image data such that a density irregularity is corrected on the basis of light amount data and/or optical characteristic data for each of the pixels for the line heads, according to a correction value created on the basis of the light amount data and/or optical characteristic data for each of the pixels of the line heads.
