Abstract
An optical scanning device includes: a polygon mirror deflecting light beams; and a plurality of reflective mirrors reflecting the light beams so as to guide the light beams to respective photosensitive drums. A first fθ lens is provided on an optical path of the light beam from the polygon mirror to a first reflective mirror. The optical path of the light beam reflected by a third reflective mirror crosses the optical path between the first reflective mirror and a second reflective mirror.
