IMAGE READER, AND IMAGE FORMATION DEVICE INCLUDING THE SAME

PROBLEM TO BE SOLVED: To correct the inclination of a reading object region even when a side of a document and that of a reading object region included therein are not parallel to each other. SOLUTION: This image reader starts transport of a document to acquire thickness information indicative of a thickness distribution of the entire document by a document thickness sensor, and stores the thickness information in an RAM. At the same time, the image reader reads an image of the document, and stores image data thereof in an image storage device. Thereafter, the image reader identifies a reading object region from the thickness information in the RAM, calculates the angle of inclination of the reading object region from its end position, and corrects the inclination of the reading object region in accordance with the inclination angle.
