ABSTRACT:
A polygonal mirror for use as a light beam deflector or scanner in an image exposure device includes a support on which a polygonal mirror body is mounted such that it is positionally limited thereby at positions near angular corners between mirror facets of the polygonal mirror. The polygonal mirror body may have a plurality of through holes defined therein on radial lines interconnecting said axis and said angular corners so that said polygonal prism body is subject to a substantially uniform moment of inertia about said axis upon rotation thereof. The holes may be filled with cores which are made of a material having a density smaller than the density of the material of which said polygonal prism body is made. Alternatively, a sheet of resin may be disposed on at least one of axially opposite surface of said polygonal prism body.
