Abstract
The image forming optical system is capable of forming an image on a conjugated plane on a reduction side as an intermediate image and re-forming the intermediate image as a magnified image on a conjugated plane on a magnification side. The image forming optical system includes: a first adjustment group that moves along an optical axis in adjusting an image formation position of a region of the magnified image including a farthest point from the optical axis; and a second adjustment group that moves along the optical axis in adjusting an image formation position of a region of the magnified image including a nearest point from the optical axis. An optical element disposed closest to the magnification side is a lens. The second adjustment group has a positive refractive power as a whole, and is disposed closest to the reduction side.
