Abstract:
An optical scanning device that scans a target surface with light, includes: a light source; a deflector that deflects light of the light source; and an optical system that forms an image of light deflected, wherein the deflector includes: a polygon mirror that reflects and deflects light of the light source; a motor that rotates the polygon mirror; and a case body that airtightly houses the polygon mirror and the motor, the case body includes a cylindrical inner wall, and the inner wall includes a rectifier that guides, from one to the other of a first space and a second space, an air flow generated by rotation of the polygon mirror in a space surrounded by the inner wall, and the first space is located on the motor side with respect to the polygon mirror and the second space is located on an opposite side of the first space.

Claim (Index 2):
The optical scanning device according to  claim 1 , wherein the rectifier includes at least one wing-like surface that radially projects from the inner surface of the inner wall and obliquely extends toward a rotation axis of the polygon mirror in a range from the first space to the second space.
