An object is to provide a image projection device which has a small size but can project an image having a high image quality. To achieve the object, in an image projection device, a reflection part which reflects a light flux from a light source is, while being rotated around a first axis by non-resonance driving, rotated by resonance driving around a second axis which is substantially perpendicular to the first axis, and thereby the light flux is deflected in a two-dimensional direction. By controlling the rotation of the reflection part, a correction for suppressing an image distortion along one scanning direction on a projection surface, and a correction for keeping substantially constant a scanning speed of the light flux along the other scanning direction on the projection surface, are performed. Here, the relationship of 10°<&thetas;<70° is satisfied, where &thetas; represents an angle of inclination of the light flux, which is projected to the projection surface, toward the other scanning direction relative to a normal line of the projection surface, in a case where the reflection part is in a central position of the rotations around the first and second axes.
