Abstract
An optical scanning apparatus includes a deflecting member that deflects and scans a light beam emitted from a light source, an optical element that scans and images the light beam on a medium to be scanned; and an opening member being disposed in a vicinity of the medium to be scanned. The opening member restricts both a scanning direction of the scanned and imaged light beam and a direction perpendicular to the scanning direction of the light beam.
