Light scanning apparatus and image forming apparatus including the same

Abstract

A light scanning apparatus according to the present disclosure includes a deflecting unit configured to deflect a light flux from a light source to scan a surface in a main scanning direction, and a first optical system configured to guide the light flux deflected by the deflecting unit to the surface to be scanned, in which a width of the light flux immediately before being incident on a first deflecting surface of the deflecting unit is smaller than a width of the first deflecting surface in a main scanning cross section, and only a part of the light flux incident on the deflecting unit is deflected toward the surface to be scanned by the first deflecting surface when the first deflecting surface is at a first angle in the main scanning cross section.

Dependencies are inferred from the claim text.
