Abstract:
1. An optical scanning device that scans a scanning surface using a light flux, the optical scanning device comprising: a light source including a plurality of light emitting elements arranged in two-dimensional array; a deflecting unit that deflects a plurality of light fluxes emitted from the light source; a coupling optical system that is provided between the light source and the deflecting unit, the coupling optical system including a scanning optical system that condenses the light fluxes deflected by the deflecting unit on the scanning surface; a housing that house the coupling optical system and on which housing the coupling optical system is fixed; and an intermediate member that is arranged between the housing and the line-imaging element, wherein surfaces of the line-imaging element and the intermediate member that are in contact with each other are flat and perpendicular to a main-scanning direction.
