Claim:
1. An image projector comprising: an image display element configured to display an original image; a first deflector configured to deflect a first optical path through which light from a light source passes, and to form a second optical path; a second deflector configured to deflect the second optical path and to form a third optical path; a shifter configured to shift a projection lens in a direction from the third optical path toward the first optical path and in a direction from the first optical path toward the third optical path, which is orthogonal to an optical axis of the projection lens, the projection lens projecting light that has passed the image display element, the first deflector, and the second deflector; and a holder configured to integrally hold the projection lens, the shifter, and the second deflector, wherein the shifter is configured so that, in relation to the third optical path, a shiftable amount of the projection lens in a direction toward the first optical path is larger than a shiftable amount in a direction opposite to the direction toward the first optical path.
