Abstract
An image forming apparatus has an image forming unit and a feeding unit for feeding a recording material at a predetermined speed to the image forming unit. A reflective type sensor reads irradiated light reflected off of the recording material and an image reading unit reads the light so as to obtain a surface image of the recording material so that a feed control unit can control the feeding of the recording medium so that a moving distance is shorter and in the case of feeding it at a predetermined speed while the recording material is read by the image reading unit. In the image forming apparatus a reflective type determination unit determines a predetermined attribute of the recording material using the surface image of the recording material read by the image reading unit so that the image forming apparatus can determine a kind of recording material based on the attribute obtain so as to form the image on the recording material.
