Abstract:
1. An image processing apparatus comprising: an emitter which has a plurality of light emitting devices arranged in a sub-scan direction; a former, arranged to form an image on a photosensitive member by multi-passed scanning an identical region on the photosensitive member in a main scan direction using light beams output from the respective light emitting devices of said emitter; an input section, arranged to input image data of an image to be formed by said former; a divider, arranged to divide the image data input by said input section into image data for respective scans in the multi-passed scans using a mask pattern generated based on amounts of deviation from scan lines of the light beams output by the respective light emitting devices; and a supplier, arranged to supply the image data divided by said divider to said emitter in accordance with scans of said former.
