A light scanning apparatus includes a scanner 104 which scans a coherent light beam from a light source 101, a light beam component generator 110 which divides the coherent light beam outgoing from the scanner 104 into a plurality of light beam components, and an optical system 105 which collects the plurality of light beam components so that they are incident on a scan surface 106 at an incident angle different from each other, and superposes the light beam components at an identical position on the scan surface.
