ABSTRACT:
Rays of light emitted from a light source are converged into a light beam by a converging optical system. The converged light beam is focused in one direction by a first focusing optical system into a linear image having a longitudinal direction corresponding to a main scanning direction in a light beam scanning device. A light deflector for deflecting the light beam has a deflecting surface disposed near a point where the linear image is focused by the first focusing optical system. The deflected light beam is focused as a light spot on a scanned surface by a light beam scanning lens serving as a second focusing optical system. The focused light spot scans a surface at a substantially constant speed. the light beam scanning lens comprises a single-element lens having a cylindrical surface facing the light deflector and a toric surface facing the surface which is scanned by the focussed light spot.
