  • Image forming media containing reflecting pigment
    Patent number: 7666562
    Abstract: The invention relates to an image forming media composition including an infrared reflecting pigment. The infrared reflecting pigment may be one that substantially absorbs light in the visible spectrum of about 400-700 nanometers and reflects greater than about 5.0% of light within the wavelength of about 700-2500 nanometers. The infrared reflecting pigment may therefore be combined with pigments such as carbon black in a toner formulation and provide the ability to control toner thickness level within a device such as a toner patch sensor.
