Abstract: A light source emitting a light flux; a coupling optical system couples the light flux from the light source to a subsequent optical system by transforming it into a parallel light flux, an approximately convergent light flux or an approximately divergent light flux; a light deflector reflects the light flux from the coupling optical system with a deflection reflective surface, and deflects it; a scanning and imaging optical system condenses the deflected light flux from the light deflector onto a surface to be scanned as a beam spot; and a correcting optical system is provided for self correcting shift of focal position of the beam spot on the surface to be scanned occurring due to environmental change or the like. The correcting optical system comprises at least one pair of a resin-made lens having an anamorphic surface having a negative power in each of main scanning direction and sub-scanning direction and a glass-made lens having an anamorphic surface having a positive power at least in sub-scanning direction, and is disposed between the coupling optical system and deflection reflective surface.

Abstract: An optical scanning apparatus is constructed such that a light beam from a light source is formed into a linear image extending in a main scanning direction and is caused to be deflected at a constant velocity by virtue of a light deflecting system having a deflective reflecting surface which is located in a vicinity of an image formation position of the linear image. The deflected light beam is allowed to transmit through a scanning image formation lens so as to be converged into a beam spot on a surface to be scanned, thus causing the beam spot to scan the surface to be scanned at a constant speed. The scanning image formation lens is formed by more than two lens elements and has at least one special surface special surface in which a sub-scanning curvature changes in a main scanning direction according to a distance from an optical axis toward a periphery of the lens surface such that a line passing through centers of curvature in the sub scanning curvature is curved, and at least one of the special surfaces is formed so that the change of a sub-scanning curvature is non-symmetrical in the main scanning direction and the curvature has at least two or more than two extreme values.
