Abstract

A scanning optical apparatus includes an image forming unit disposed between a medium to be scanned and a diflective reflection surface of a rotary polygon mirror so as to make a light beam deflected by the rotary polygon mirror form an image on the medium to be scanned and as to maintain the deflective reflection surface and the medium to be scanned in a geometrically optical conjugate relationship in a plane perpendicular to a surface to be deflectively scanned with the deflected light beam, and a vibration unit for vibrating another image forming optical unit in a direction of an optical axis of light beam emitted from a light source in synchronization with a deflection scanning of the rotary polygon mirror so as to vibrate an image forming position, at which the aforementioned another image forming optical unit forms a linear image, along the optical axis of the emitted light.
