摘要： An optical scanning device includes a light source, a photodetector, an optical element group, and a polygon mirror. The light source is configured to emit laser light. The photodetector is configured to detect a beam formed with the laser light. The optical element group is configured to guide the beam to the photodetector. The polygon mirror is configured to perform deflection scanning on the beam, which deflects the beam from a first end in one direction of a main scanning direction to a second end on a side opposite to the first end of the main scanning direction. The beam is incident on the same side of the photodetector when the beam is deflected toward the first end and the second end by the polygon mirror.
