Image forming apparatus

摘要

An image forming apparatus includes a photoreceptor; a plurality of laser beam generation means for generating a plurality of laser beams, respectively; and an optical system in which the plurality of laser beams pass through and scan simultaneously a plurality of lines on the photoreceptor, and thereby dot images are formed on the photoreceptor. The difference in wavelength among the plurality of laser beams is less than a diameter of one dot of laser beam.
