Abstract
An optical scanning device is constituted without using any arc sin .theta. correction lens, while maintaining quality of an image. The optical scanning device comprises an optical flux generator, a resonance-type deflection element, a drive signal generator and a dot clock generator that is configured to sequentially generate dot clocks which satisfy a first, second and third condition, wherein the optical flux generator radiates the optical fluxes having brightnesses corresponding to the clock cycles of the dot clocks generated by the dot clock generator.
