ABSTRACT:
A multi-beam scanning apparatus includes a light source unit for emitting a plurality of beams, a beam deflector for deflecting the plurality of beams from the light source unit, and a common scanning image-forming optic for converging the plurality of deflected beams so as to form a plurality of beam spots for simultaneously scanning a scanned surface, a plurality of scan lines respectively described by the plurality of beam spots being isolated from each other in a sub-scanning direction, wherein the plurality of scan lines are bowed in the same direction.
