ABSTRACT:
In an optical scanner, a light beam deflected by an optical deflector is reflected on a reflective image forming element and is converged as a light spot onto a scanned face through an elongated lens to perform an optical scanning operation. The reflective image forming element is formed by a plastic material and has a function for approximately converging the deflected light beam onto the scanned face with respect to a main scan-corresponding direction. The reflective image forming element also has a function for approximately moving the light spot at an equal speed. The elongated lens is formed by plastic and has a function for converging the deflected light beam onto the scanned face with respect to a cross scan-corresponding direction in cooperation with the reflective image forming element. The elongated lens also has negative refracting power with respect to the main scan-corresponding direction. In this optical scanner, the influence of a change in temperature on optical scanning characteristics can be reduced.
