Abstract: A light beam deflected by a polygon mirror (20) is incident substantially perpendicularly on a trapezoidal reflecting prism (33) having an incidence surface (33a) and two reflection surfaces (33b, 33c). Then, the light beam incident on the reflecting prism (33) is totally reflected at the first reflection surface (33b) toward the second reflection surface (33c). Next, the totally reflected light beam is totally reflected at the second reflection surface (33c) toward the incidence surface (33a) and is emitted from the incidence surface (33a) in the opposite direction from the incident direction. The emitted light beam passes through a cylindrical lens (34) and is reflected and directed toward a scan surface (40) by a cylindrical mirror (35). The reflected light beam forms a scanning spot-on the scan surface (40).
