Abstract
A light scanning apparatus including: a light source; a rotary polygon mirror configured to deflect a light beam emitted from the light source; an optical component of an incident optical system configured to introduce the light beam to the rotary polygon mirror; an optical box configured to contain the rotary polygon mirror and the optical component; and a supporting base installed between the light source and the rotary polygon mirror and configured to support the optical component, wherein the supporting base includes: a first dust-proof member configured to seal a boundary portion between the optical box and the supporting base; and a protrusion configured to enter an opening, which is formed in a side wall of the optical box from the inside of the optical box in a state in which the supporting base is mounted to the optical box, the light source being fixed to the opening.
