置。[Claims for Utility Model Registration] (1) A light source that emits a laser beam, a laser beam deflection means for deflecting the laser beam in a predetermined direction and main scanning, and a laser beam deflected by the laser beam deflection means. In a laser beam scanning device having a transmission plate disposed in an exit window, the polarization direction of the laser beam is substantially perpendicular to the scanning direction by the scanning means, and the transmission plate is arranged in a sub-scanning direction with respect to the scanning direction of the laser beam. A laser beam scanning device characterized in that the laser beam scanning device is arranged to be inclined by an angle β with respect to the angle β, and the angle β is set to 20°≦β≦65°. (2) The laser beam scanning device according to claim 1, wherein the transmitting plate is not coated with a coating that reduces reflectance. (3) The laser beam scanning device according to claims (1) and (2), wherein the transmission plate is made of glass or resin.
