Abstract:
A light scanning apparatus includes a laser light source, an anamorphic element converging a laser beam from the laser light source in a sub-scan direction, a deflector deflecting and scanning the laser beam, an image-forming optical system converging the deflected laser beam in a scan direction onto a scan target surface, and a reflective member between the image-forming optical system and the scan target surface to reflect the laser beam onto the scan target surface. When an F value of axial beam in the scan direction is Fno, an F value of beam at a maximum image height in the scan direction is Fno′, and an incidence angle of beam at the maximum image height onto the scan target surface in the scan direction is α, the following Equation (1) is satisfied: { 1 -( 1 -cos α 4 )/√M}/cos α 4 ≥Fno′ 2 /Fno 2 ≥1 /cos α 4    ( 1 ) where M is an arbitrary real number that is √ 2  or greater and  2  or smaller.

Claim (Index 10):
The light scanning apparatus according to  claim 3 , wherein the reflective member includes a first reflective mirror and a second reflective mirror each with an approximately planar mirror surface,\n the first reflective mirror reflects the laser beam emitted from the image-forming optical system onto the second reflective mirror, and the second reflective mirror reflects the laser beam emitted from the first reflective mirror onto the scan target surface.
