Abstract
An optical scanning device which scans a scanned surface by a plurality of light beams in a main-scanning direction includes a light source having a plurality of light-emitting portions which emit the light beams, the light-emitting portions being two-dimensionally arranged in a plane parallel to the main-scanning direction and a sub-scanning direction orthogonal to the main-scanning direction via arrangement intervals in the main-scanning direction and the sub-scanning direction, a deflector which scans the light beams in the main-scanning direction; and a scanning optical system which images the scanned light beams onto the scanned surface.
