Abstract
An optical scanning apparatus includes first and second light sources configured to emit first and second light fluxes respectively, a deflector having a reflecting surface which reflects the first and second light fluxes, and configured to deflect the first and second light fluxes in a main scanning direction, and an imaging lens configured to let the first and second light fluxes through and form an image of the first and second light fluxes on the reflecting surface of the deflector. The imaging lens has a first incident surface into which the first light flux enters at a right angle, a second incident surface into which the second light flux enters at a right angle, a first outgoing surface from which the first light flux exits, and a second outgoing surface which makes an angle with the first outgoing surface and from which the second light flux exits.
