Abstract
To provide a technique capable of improving the quality of an image to be formed.SOLUTION: An image forming apparatus that forms an image on a sheet based on image data, the image forming apparatus comprising: a photosensitive member that rotates around a rotation axis; an exposure head that includes a plurality of light emitting chips including at least a first light emitting chip and exposes the photosensitive member; and a correction unit that corrects a light emitting amount of the exposure head, wherein each of the plurality of light emitting chips includes a plurality of light emitting elements arranged in a direction along the rotation axis, the correction unit performs common light amount correction for the plurality of light emitting elements of the first light emitting chip and individual light amount correction for the plurality of light emitting elements of the first light emitting chip.SELECTED DRAWING: Figure 8
