ABSTRACT:
An image reading apparatus including a backing member arranged on the original transport path, a light source for emitting the light toward the original reading position in the original transport path in the direction of a predetermined incident optical axis, a detector capable of detecting the light reflected at the original reading position in the direction of a predetermined reading optical axis, and an image processing apparatus. The reflection surface of the backing member is configured in such a manner that the amount of the light reflected by the backing member and detected by the detector is not less than the amount of the light corresponding to a white reference value and that the amount of the light passing through the original, reflected by the backing member, re-passing through the original and detected by the detector, is not more than the amount of the light capable of preventing the imaging from the reverse side.
