Abstract
To provide a scanning optical apparatus, not requiring a lens in a complex figure, and also, capable of eliminating the bow of a beam light even when a plurality of correcting lenses are in an identical figure. Beam light L falls on Cross section K perpendicular to Rotational axisof Polygon mirrorat an angle of 2° or less. When such an incident angle condition is satisfied, the figure of a cross section in the sub scanning direction of Scanning lensis a spherical surface figure, and also, the curvature of Incident surfaceand Outputting surfacewith respect to the sub scanning direction is changed according to the position in the main scanning direction. Furthermore, Correcting lensis arranged in a tilted (decentered) state with respect to the light axis of Beam light L.
