Polygon mirror mounting structure
 A polygon mirror mounting structure mounting a polygon mirror to an outer periphery of a rotor includes a mirror seating surface formed on the outer peripheral portion of the rotor for seating the polygon mirror thereon, and a retaining member having a ring-shaped configuration and a plurality of radially extending pawls on the outer periphery thereof for retaining the polygon mirror on the mirror seating surface. The pawls have an arcuate or tapered cross-sectional configuration and directly press the polygon mirror downwardly and radially outwardly, to thereby enable securing the polygon mirror to the rotor without providing through-holes for receiving screws in the polygon mirror.
