ABSTRACT:
An image forming apparatus includes a plurality of light-emitting element array units, a light intensity control unit, and an image data transfer unit. Each light-emitting element array unit includes a plurality of light-emitting elements, and is arranged in an at-least-two-rows staggered manner in a main scanning direction with overlapping portions overlapping in a sub-scanning direction to include a plurality of light-emitting elements continuously adjacent one to another in the at-least-two-rows staggered manner in the main scanning direction with an adjacent two overlapping light-emitting elements at each of the overlapping portions. The light intensity control unit controls light intensity of the light-emitting elements based on an overlapping degree of the adjacent two light-emitting elements at each of the overlapping portions. The image data transfer unit divides an input image data and transfers the respective image data to each one of the light-emitting element array units.
