Abstract
An optical scanning apparatus, including: a deflector including deflection surfaces and configured to deflect, by the deflection surfaces, light beams respectively emitted from light emitting portions for scanning in a main scanning direction; an imaging optical system configured to guide the light beams deflected for scanning by the deflection surfaces to a surface to be scanned; a light source including the light emitting portions arranged so as to be separated from each other in a sub-scanning direction perpendicular to the main scanning direction and an optical axis direction of the imaging optical system; and a controller configured to control the light source in such a manner that a difference between scanning start timings of the light beams at two adjacent deflection surfaces among the deflection surfaces is different from a difference between scanning start timings of the light beams at other two adjacent deflection surfaces among the deflection surfaces.
