LIGHT BEAM SCANNING APPARATUS ABSTRACT OF THE DISCLOSURE A light beam scanning apparatus comprises a plurality of semiconductor lasers, collimator lenses for converting a plurality of laser beams emitted by the semiconductor lasers into parallel rays, a common converging optical system for converging the laser beams to a common spot, and a common light deflector for deflecting and scanning the laser beams. Or, a light beam scanning apparatus comprises a plurality of semiconductor lasers positioned so that laser beams emitted by the semiconductor lasers focus on a common spot, a plurality of converging optical systems respectively positioned so as to correspond to the semiconductor lasers for converging the laser beams to the spot, and a common light deflector for deflecting and scanning the laser beams.
