ABSTRACT:
Disclosed is an optical scanning device which includes a light source device, a deflecting system for deflecting a light beam emitted from the light source device, and a scanning optical system for scanning a surface to be scanned, with the light beam deflected by the deflecting system, wherein the scanning optical system includes a scanning optical element disposed so that, with respect to a sub-scan direction, a principal ray of the deflected light beam passes a portion other than an optical axis, wherein the scanning optical element has a sagittal aspherical amount changing surface in which an aspherical amount of a sagittal changes along a main scan direction of the scanning optical element, and wherein, throughout the whole surface to be scanned, the position in the sub-scan direction upon which the deflected light beam impinges is made even.
