ABSTRACT:
The disclosure of the current invention describes a compact optical system for and method of forming an image on an intermediate image-forming surface such as a photoreceptor drum at a high speed. An image-forming light source such as a laser light source is placed between an image-focusing element such as a focusing mirror and an image-scanning unit such as a polygon mirror. According to one preferred embodiment, the image-forming light source is placed in a scanning area defined by a predetermined scanning angle of the image scanning unit.
