系。[Claim for Utility Model Registration] In a scanning method in which a laser beam is reflected and deflected by a rotating polygonal mirror to scan a scanning line on a scanning surface, a laser beam that passes approximately at the center of the main scanning line and extends onto a plane perpendicular to the main scanning line. A laser beam scanning optical system is characterized in that a laser beam is made incident on a rotating polygon mirror, and the angle of incidence is set as small as possible.
