Abstract
In a scanning optical apparatus, a light beam emitted by a light source is caused to be obliquely incident on a deflection surface of an optical deflector in a sub scanning section through an optical device to form an image of the light beam deflectively reflected by the optical deflector on a surface to be scanned by an imaging optical system. A lateral magnification of the imaging optical system in a sub scanning direction is caused to change in accordance with a distance away from the on-axis to an off-axis along the main scanning direction.
