Abstract
A light scanning apparatus is disclosed having: a light source portion, a correction deflecting element for finely deflecting a light beam emitted by the light source portion in an auxiliary scanning direction, a scan deflector for deflecting the light beam from the correction deflecting element in a principal scanning direction, a lens system disposed between the correction deflecting element and the scan deflector and adapted to bring both of them in an optically conjugate relation, and a scanning lens for imaging the light beam deflected by the scan deflector onto a scanning surface.
