Abstract
A scanning optical apparatus includes: two light source units; a deflecting unit for deflecting two light beams for scanning; and two imaging optical systems disposed corresponding to the two light beams, in which: the two imaging optical systems form images of the two light beams on photosensitive members of different hues; the two imaging optical systems are disposed to be opposed with respect to the deflecting unit in a sub-scanning cross section; and a reflectance of a first reflecting optical element disposed in an optical path between the photosensitive member and the deflection surface passed by a light beam corresponding to an image of a hue having low brightness is lower than a reflectance of a second reflecting optical element disposed in an optical path between the photosensitive member and the deflection surface passed by a light beam corresponding to an image of a hue having high brightness.
