Abstract
An electrophotographic image forming apparatus having an LED array with a plurality of light emitting elements aligned in a main-scanning direction and a convergent lens array for imaging light emitted from the light emitting elements on a photosensitive member. In order to correct density unevenness caused by positioning errors of the lens array, the light quantity emitted from each of the light emitting elements is adjusted such that the total difference from a target value will be closer to zero.
