Abstract
An image forming apparatus includes a light emitting array composed of a plurality of light emitting elements that emits light fluxes. An imaging element array may be provided so as to perform imaging with the light fluxes on a prescribed plane. A three dimensional exposure intensity distribution of the light flux is obtained per each light emitting element. A prescribed attribute is obtained from each of the exposure intensity distributions. A plurality of comparison values for the entire exposure valid region may be obtained from different units which consist of two or more successive attributes. Prescribed light emitting quantities enabling all of the comparison values to fall within a prescribed range may be determined and set to respective light emitting elements.
