Abstract
A laser scanning device includes: a plurality of laser light sources, each of the plurality of laser light sources emitting a laser light having a light intensity distribution having an elliptical shape; an aperture through which the laser lights emitted from the plurality of laser light sources pass; and a scanning mirror for reflecting the laser lights from the aperture to a scan position. A position of the aperture is adjustable in a first adjustment direction. The plurality of laser light sources are oriented so that long axis directions of the light intensity distributions of the laser lights emitted by the plurality of laser light sources are parallel to the first adjustment direction at positions at which the laser lights emitted by the plurality of laser light sources enter the aperture.
