Abstract
PURPOSE:To decrease the number of components by adhering a metallic film to a reflecting surface for a deflected laser beam, and uniting the reflecting surface with the scanning lens in level with the reflecting surface. CONSTITUTION:The laser light beam 6 is deflected by a polarizing polygon mirror 2 and enters the scanning lens 10 from a surface S1 on an incidence lens surface 15. The lens 10 has its lens main body 11 molded out of synthetic resin, a triangular plate part 13 is aligned with the surface S1, and a projection lens surface 16 is arranged opposite a photosensitive body 5. The incident beam travels in the plate part 13 to reaches the arrival surface and deflected downward and reflected by 90 deg. by the reflecting surface 12 where the metallic film 18 is adhered to become a laser beam 6a. The beam 6a scans on the photosensitive drum 5 from the projection lens surface 16. Further, the incidence lens surface 15 is concave, the projection surface 16 is convex, and they are both aspherical. In said constitution, the reflecting surface is united with the lens main body to decrease the number of components.
