ABSTRACT:
An optical scanning apparatus includes a rotatable polygonal mirror for deflecting first and second laser beams, which are incident on the polygonal mirror at diff(rent positions with respect to a rotational direction of the polygonal mirror; a first optical member for transmitting the first laser beam; a second optical member for transmitting the second laser beam; a laser beam blocking member, disposed between the first optical member and the second optical member, for blocking the first laser beam reflected by the first optical member to prevent the first laser beam reflected by the first optical member from being incident on the second optical member.
