Abstract
A light scanning device includes a semiconductor laser which emits a laser beam in response to an image forming signal, an optical deflector which scans the laser beam emitted from the semiconductor laser in a main scanning direction, and a liquid crystal deflecting element which changes the scanning position of the laser beam emitted from the semiconductor laser while desynchronized with output of the image forming signal, thereby to correct the scanning position of the laser beam in a sub-scanning direction.
