Abstract:
An image scanner includes: a light source that irradiates, with light, a recording medium on which an image is formed; a light receiving portion that receives light reflected by the recording medium; a reflecting portion that has plural reflecting surfaces respectively disposed at positions having different distances in an optical axis direction from the light receiving portion; and a processing portion that generates information on the image formed on the recording medium and information for measuring illumination depth of the light source, by use of the light received by the light receiving portion.
