The imaging optical system consists of a first optical system and a second optical system along an optical path in order from an enlargement side to a reduction side. An intermediate image is formed between the first optical system and the second optical system. The imaging optical system satisfies a conditional expression of 1.73<tan ωm<5 regarding a maximum half angle of view ωm of the enlargement side. The imaging optical system satisfies predetermined conditional expressions regarding a curvature radius of an LA lens disposed adjacent to the reduction side of a longest lens spacing that is a longest spacing among spacings on an optical axis between lenses in the imaging optical system and a curvature radius of an LB lens disposed adjacent to the reduction side of the LA lens.
An imaging optical system that forms an intermediate image at a position conjugate to a reduction-side imaging plane and re-forms the intermediate image on an enlargement-side imaging plane,
