The second reading unit is disposed in the document conveyance path at a reading position that is different from a reading position of the first reading unit and reads an image on a second side that is different from the first side on the document. The determination unit determines whether the document is a color document, according to whether a color image is included in an image in a predetermined region of the first side read by the first reading unit, and in an image in a region that is different from the predetermined region in the first side and read by the second reading unit.
