ABSTRACT:
An image forming apparatus and method use interlace scanning of plural light beams by deflecting the plural beams with a rotating polygon onto a recording medium. Corrections are made to the scan envelope to compensate for errors due to perceived imperfections in the spot profile or aberrations in the optical and mechanical systems used to scan the spot. The corrections are performed by adjusting intensity of gaussian components of the envelope according to a look up table.
