Abstract:
1. A light scanning unit comprising: a light source unit to emit a light beam according to an image signal; a light deflector to scan and deflect the light beam emitted from the light source unit; an imaging optical system that comprises at least one imaging lens arranged on an optical path from the light deflector to a to-be-scanned surface and imaging the light beam scanned and deflected by the light deflector on the to-be-scanned surface, and first and second reflection members arranged on the optical path from the light deflector to the to-be-scanned surface; a housing to accommodate the light source unit, the light deflector, and the imaging optical system; and first and second assembly members to press and fix the first and second reflection members on the housing, wherein the first and second assembly members respectively press and fix the first and second reflection members on the housing by respectively pressing the first and second reflection members in respective directions in which a curvature of a scanning line due to the inclination of the first reflection member offsets a curvature of a scanning line due to the inclination of the second reflection member.
