ABSTRACT:
An optical scanning device of the invention includes: n-odd (n≧2) light sources disposed at different positions at least in a sub scanning direction; a light source driving control part configured to control a light emitting state of the light source; and a sub-scanning pixel position detecting part configured to depict one pixel with m-odd (n≧m≧2) light sources of the n-odd (n≧2) light sources and to detect a deviation in position of the one pixel in a sub scanning direction, wherein the light source driving control part is configured to correct the deviation in position of the one pixel in the sub scanning direction at a resolution equal to or higher than a density of the pixel, depicted with the m-odd light sources, by controlling the light emitting state of the m-odd light sources on the basis of a result of detection with the sub-scanning pixel position detecting part.
