Abstract
The light scanning apparatus includes: a deflection element including first and second deflection surfaces; a rotor including a top surface facing the deflection element; a first imaging optical system including a first imaging lens; a second imaging optical system including a second imaging lens arranged to face first imaging lens; first and second shielding members. The first shielding member is arranged at a position where an edge portion thereof on a side closer to top surface in a sub-scanning direction blocks light reflected by first imaging lens. The second shielding member is arranged at a position where an edge portion thereof on a side closer to top surface in sub-scanning direction blocks light that has passed by first shielding member and been reflected by top surface.
