Multi-beam scanning device
A multi-beam scanning device is provided with a light source that emits a plurality of light beams, a polygonal mirror that deflects the light beams emitted by the light source to scan, and an optical system that converges the deflected light beams on a plurality of objects to be scanned. The optical system includes an optical path turning system that turns optical paths of the deflected light beams, respectively. The optical path turning system is constructed such that optical path lengths of the optical path of the deflected light beams are the same, and one of the optical paths directed to an object located farthest from the polygonal mirror consists of two linear paths and one turning portion at which a beam is deflected.
