Original Abstract Submitted
An optical scanning device includes first and second light sources, a rotational polygon mirror reflecting first and second luminous fluxes, and first and second lenses. The polygon mirror reflects the second luminous flux in an opposite direction to the first luminous flux and the second lens is disposed on a side opposite to the first lens as a boundary of the polygon mirror. A shielding member including a shielding wall shielding first and second optical paths from the first and second light sources toward the polygon mirror, respectively. The shielding member is rotatable about a rotating shaft and moves between a shielding position and a retracted position. As viewed in a rotational axis direction of the polygon mirror, the rotating shaft is positioned between the first and second optical paths and an axis of the rotating shaft extends in a direction crossing to an optical axis of the first lens.
