Abstract

An optical scanning device includes a light source, a scanning member, a converging lens, a first aperture, a second aperture, and a support member. The first aperture is provided between the converging lens and the scanning member and includes a first opening portion configured to restrict a beam path width in a main scanning direction of the laser beams emitted from the light source. The second aperture is provided between the light source and the converging lens and includes a second opening portion and a cylindrical portion. The second opening portion is configured to restrict a beam path width in a sub scanning direction of the laser beams emitted from the light source, and is formed in the cylindrical portion. The support member includes a cylinder supporting portion that pivotably supports the cylindrical portion of the second aperture.
