Abstract
An optical scanning device includes a first light source, a second light source, a first aperture, a second aperture, a third aperture, and a deflector. The first light source emits a first light flux. The second light source emits a second light flux. The second light flux is separated from the first light flux by an opening angle in a main scanning direction. The first aperture shapes a beam shape of the first light flux in a sub-scanning direction. The second aperture shapes a beam shape of the second light flux in the sub-scanning direction. The third aperture shapes the beam shape of the first light flux and the beam shape of the second light flux. The deflector deflects the first light flux and the second light flux at positions separated in the sub-scanning direction on a surface.
