摘要：
By providing a step in a pressing member for pressing a recording material P to a reading surface of an image-pickup unit, surface images in a tight contact area and a non-tight-contact area are picked up. By identifying the type of the recording material P based on the two surface images, the accuracy of identifying the recording material is improved without using a plurality of sensors.
