<p>PROBLEM TO BE SOLVED: To provide an optical scanning device achieving reduction in positional deviation in relative positions of a plurality of light beams in main scanning directions due to temperature change.SOLUTION: The optical scanning device includes; a plurality of light sources 21; a plurality of light source units 6 supporting the plurality of light sources, respectively; a deflecting member 11 for defecting a plurality of light beams in order to scan a plurality of photoreceptors 10 with the plurality of light beams emitted from the plurality of light source units; and a housing 71 for supporting the plurality of light source units and the deflecting member. The housing is provided with an opening 62a to which the plurality of light source units are fixed. Of the plurality of light source units, first light source units are fixed to the opening on one side while second light source units are fixed to the opening on the other side.</p> |
