Abstract
The invention is objected to perform fixing in an optimum fixing condition even with various kinds of recording materials or the like while improving usability by discriminating the kinds of recording materials. An image reading sensorincludes a reflective LED, a transmissive LEDdisposed on the opposite side relative to a recording materialfor detecting the transmitted amount of light, a CMOS area sensor, and an imaging lens. The light from the reflective LEDas a light source is applied toward the surface of the recording material, and the reflected light from the recording materialis collected via the lensand an image is formed on the CMOS area sensor. The LEDis disposed so as to apply LED light to the surface of the recording materialdiagonally at a predetermined angle.
