摘要:
An optical scanning device and an image forming apparatus using the same are provided to obtain an image of high picture quality at a high speed. An image forming optical system(LB) includes at least one sheet of image forming optical element for forming an image on a target scan surface with respect to an optical flux deflected by a deflecting unit. At least one sheet of reflective optical element is disposed between the image forming optical element and the target scan surface. The deflected optical flux pass through the first and second transmissive surfaces of the image forming optical element, reflected by the reflective optical element, and then passes through the third and fourth transmissive surfaces of the image forming optical element. An aperture stop(2) restricts the light beam passing therethrough to shape the beam profile, a lens system(cylindrical lens)(4) has a predetermined power only in a sub-scan section.
