Abstract
An optical scanning device includes a deflector that deflects light fluxes emitted from light sources and rotates in a first direction, optical systems that direct deflected light fluxes onto subject surfaces, and a member that prevents a flare beam reflected by one of the optical systems from entering another one of the optical systems. The deflector includes first edges in the first direction and the member includes second edges arranged in a second direction perpendicular to the first direction. The second edges are out of alignment with each other in the first direction so that a first edge does not pass all of the second edges simultaneously.
