Abstract
By magnifying a beam light from a polarizer by a scanning lens (also referred to as a magnifying lens) and a decentered lens (serving as a correcting lens) which is a lens arranged in a side of a scanning surface with an axis thereof decentered relative to a light axis of the beam light, a spherical aberration normally exacerbated by magnifying the beam light by the scanning lens is suppressed. In addition, even if the scanning lens and the correcting lens are arranged close to the polarizer, main scanning magnification is kept small and spherical aberration is suppressed.
