Abstract
An optical scanning device is configured in such a manner that, of four light beams for colors corresponding to black, cyan, magenta, and yellow, the angle of the reflection surface of the last folding mirror disposed in the optical path of a light beam corresponding to an image in black having the lowest brightness and the highest visibility is closest to vertical, and further, the angle of the reflection surface of the last folding mirror disposed in the optical path of a light beam corresponding to an image in yellow having the highest brightness and the lowest visibility is closest to horizontal. It is thus possible to reduce a color shift in the color image caused by reflecting a light beam having passed through the correction lens on the last folding mirror.
