Abstract:
1. A light scanning apparatus configured to irradiate a surface to be scanned with a light beam, the light scanning apparatus comprising: a light source configured to emit the light beam; a deflector configured to deflect the light beam emitted from the light source so that the light beam scans the surface to be scanned; an optical element configured to lead the light beam deflected by the deflector to the surface to be scanned; a housing configured to hold the light source, the deflector, and the optical element, the housing including fibers; and a rib formed integrally with a bottom portion of the housing on which the deflector and the optical element are disposed, the rib being provided to stand on the bottom portion between the deflector and the optical element in order to suppress a deformation of the housing in a scanning direction in which the light beam scans the surface to be scanned, wherein the fibers of the rib are oriented along the scanning direction, and the fibers of the bottom portion are oriented along the bottom portion and in a direction perpendicular to the scanning direction.
