An image projection apparatus includes an intermediate image forming member configured to form an intermediate image from light emitted by a light source device; and a plural-film optical member on which image light that forms the intermediate image is incident. The image projection apparatus uses the image light that is incident on the plural-film optical member to project an image, an image rotational position relationship in a rotational direction around an image center axis between the image that is projected and the intermediate image is such that a difference is present in image rotational positions, and the plural-film optical member is set in such a manner that a polarization axis of the image light incident on the plural-film optical member is parallel or perpendicular to a plane of incidence of the image light with respect to the plural-film optical member.
