ABSTRACT:
A tilt error corrective scanning optical system for a system having a deflection device for deflecting and reflecting a light beam, comprising a linear image forming optical device for causing a light beam emitted from a light source to form a linear image on the surface of the deflection device, and an image projection optical device for causing the deflected beam of the linear image to form restored image on an objective surface while maintaining constant beam scanning speed. The image projection optical device consists of a single toric lens having toric surfaces on the both sides thereof, the first toric surface faced to the deflection device is concave in both directions parallel and perpendicular to the scanning plane and the second toric surface opposite to the first toric surface is convex in the both directions.
