Abstract
In an optical scanning device having a lens within a housing, the attachment of the lens to the housing is facilitated. The occurrence of lens distortion and warpage is prevented when the lens is formed by an injection molding apparatus. The lens is a long lens elongated in the main scanning direction for a photoreceptor and has support ends formed at both ends of outside of the lens effective area in the longitudinal direction, and one of the support ends formed at both the ends has a first projection that projects from a side surface in a thickness direction of the lens. The lens is positioned and equipped in the longitude direction of the lens relative to the housing supporting the lens with the first projection in the optical scanning device.
