Abstract:
1. An image forming apparatus, comprising: a plurality of light-emitting element array units configured to cover an area with a predetermined width, each one of the light-emitting element array units comprising a plurality of light-emitting elements, the plurality of light-emitting element array units being 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; at least one light intensity control unit configured to control light intensity of the adjacent two overlapping light-emitting elements and other of the plurality of light-emitting elements around the adjacent two overlapping light-emitting elements, based on an overlapping degree of the adjacent two light-emitting elements at each of the overlapping portions; and an image data transfer unit configured to divide an input image data and to transfer the respective image data divided for each one of the plurality of light-emitting element array units to the each one of the plurality of light-emitting element array units.
