Abstract:
A light scanning device wherein a plurality of light beams are irradiated, the plurality of irradiated light beams are deflected by a deflecting means and divided scanning is performed on each scanning line of a photoconductor by the deflected plurality of light beams,said light scanning device comprising:a detection means for detecting light beams passing through at least one of either a predetermined position in front of a position where the light beam first strikes the image forming range of said photoconductor, or another predetermined position behind a position where the light beam last strikes the image forming range of said photoconductor, when said scanning line is scanned;an oscillating means for oscillating a specified number of clocks in an interval of time from when the light beam is detected by said detecting means until the light beam is detected again; andan adjusting means for adjusting the plurality of light beams so as to be irradiated according to the clocks oscillated by said oscillating means.
