Abstract:
At least a part of a first thrust-direction force generated by air resistance received by at least one surface of reflection surfaces arrayed in a rotating direction of a polygon mirror 35 and tilted with respect to a rotation axis 35p of the polygon mirror 35 is canceled by a second thrust-direction force generated by air resistance received by a surface tilted with respect to the rotation axis 35p in a direction opposite to the surface where the first thrust-direction force is generated.
