プリンタ。 In a laser printer that simultaneously scans a photoreceptor with multiple light beams, there are multiple laser light sources that emit parallel light beams that connect spots on the photoreceptor, and a polygon mirror that reflects the light beam and scans it on the photoreceptor; and a polygon mirror that is disposed between the polygon mirror and the photoreceptor and has a width corresponding to the scanning range of the light beam and is projected onto the photoreceptor. A laser printer comprising a plurality of reflecting mirrors for arbitrarily adjusting the interval between laser beam spots.
