Abstract:
A laser scanning unit includes a rotary polygon mirror, a shaft support portion, a plurality of light application portions, and a plurality of scanning lenses. The plurality of light application portions are configured to cause light beams to be incident at a plurality of incidence positions different in an axial direction parallel to the rotary shaft on the rotary polygon mirror. In the laser scanning unit, the following relationship is satisfied: when, of the plurality of light beams, a specific light beam incident at the incidence position that is most distant from the shaft support portion on the rotary polygon mirror passes through an optical axis of the corresponding scanning lens, an angle between the specific light beam incident on the rotary polygon mirror and the optical axis of the scanning lens is closest to a reference angle defined in advance as a usage condition of the scanning lens.

Claim (Index 6):
The laser scanning unit according to  claim 1 , wherein,\n the following relationship is satisfied: the angle between the specific light beam incident on the rotary polygon mirror and the optical axis of the scanning lens when the specific light beam passes through the optical axis of the scanning lens is smaller than that of the other light beam.
