Abstract:
1. An optical scanning device comprising: an obtaining unit for obtaining color image data; a plurality of light sources, each light source emitting a plurality of first beams having colors associated therewith; a beam splitting unit for splitting each of the plurality of first beams into second beams; a deflecting unit including a plurality of reflecting members, each corresponding to one of the plurality of second beams and each performing deflection scanning of the second beams split from a corresponding first beam; an optical system for performing image formation, using the plurality of second beams that have been subjected to deflection scanning, on each of target surfaces for scanning, wherein the target surfaces for scanning have been assigned with different colors corresponding to the first beams from which the second beams are split, and wherein the target surfaces for scanning are provided at opposite sides of the deflecting unit in a sub-scanning direction; a light receiving unit for detecting the second beams that have been subjected to deflection scanning; a detecting unit for detecting, based on a detection result of the light receiving unit, which of the reflecting members corresponds to the second beam that has been detected; an interchanging unit for obtaining, from the color image data, data of a plurality of lines corresponding to each of the plurality of first beams and interchanging the data of the lines that have been obtained based on a detection result of the detecting unit; and a light source control unit for controlling the light sources in such a way that the light sources emit the first beams in accordance with the data of the lines that have been interchanged by the interchanging unit.
