摘要
A multi-beam scanning method for scanning a scanning surface with a plurality of beams which are formed into a plurality of beam spots separated from each other in a sub scanning direction includes providing n number of semiconductor laser array units, each of the n number of semiconductor laser array units having m number of light emitting points, where n is not equal to 1 and m is not equal to 1, coupling light beams emitted from the light emitting points of the semiconductor laser arrays, synthesizing the coupled beams with a beam synthesizing device to obtain m×n number of beams and deflecting the m×n number of beams at substantially the same time such that the deflected beams are impinged on the scanning surface.
