Abstract
A light-scanning device includes a polygon scanner having a rotatable polygon mirror which deflects a laser beam emitted from a light source, an optical image-forming element which images the deflected laser beam on a predetermined position, and an optical housing which supports the light source, the polygon scanner and the optical image-forming element, a non-rotational cylindrical shielding member for covering an upper part of the polygon scanner.
