ABSTRACT:
A scanning optical system has a beam of light which is deflected by a light deflector and which scans a scanning surface along a main scanning direction through a scanning lens system. The scanning lens system includes an anamorphic lens made of glass which has a positive power in both the main scanning direction and in a sub-scanning direction perpendicular to the main scanning direction. The positive power in the sub-scanning direction is larger than the positive power in the main scanning direction. Also included is a plastic lens having an aspherical surface in the main scanning direction.
