ABSTRACT:
A deflecting/scanning apparatus includes a deflector for deflecting/scanning a light beam from a light source unit, an optical system for focusing the light beam deflected/scanned by the deflector onto a surface, an optical box for accommodating the deflector and the optical system, and a cover for covering the optical box. An elastic member is disposed in the optical box so as to blocking flow of air entering therein. At least a portion of the elastic member is fitted in a recess portion formed on at least one of the optical box and the cover so that the elastic member is pressed by the cover.
