1. An image projection apparatus comprising:
an illumination unit which generates illumination light; a first prism which receives the illumination light from the illumination unit and performs total reflection of the illumination light; a reflection mirror which receives the illumination light from the first prism and reflects the illumination light; an image forming unit which forms an image from the illumination light that is reflected from the reflection mirror; and a second prism which performs total reflection of the image that is formed by the image forming unit toward a screen, wherein a reflection surface of the reflection mirror has a curvature so that the illumination light that is reflected from the reflection mirror is extended or reduced to correspond to an effective area of the image forming unit.
