摘要： An optical scanning device includes an enclosure having a plurality of windows covered with transparent members. The enclosure houses a plurality of light sources, a scanning portion, optical elements and a light amount attenuation portion. The scanning portion deflects each of a plurality of light beams emitted from a plurality of light sources at a constant angular speed in a main scanning direction. The optical elements constitute respective light paths from the scanning portion to the windows for the plurality of light beams, respectively. The light amount attenuation portion attenuates light amount in a light path of a first light source among the plurality of light sources in a downstream side of the position where a light beam emitted from a second light source enters as stray light. The drive portion drives the first light source so as to compensate for light amount attenuated by the light amount attenuation portion.
