Abstract
Abstract The present invention provides an imaging device and method for developing, duplicating and printing graphic media. The imaging device of the present invention is utilized in devices such as copiers, printers, game cards and the like, and comprises a substrate bearing an infrared image producing layer, a thermal image forming layer and a light source. A brief but intense flash of visible light from the light source causes latent heat properties of the infrared layer to generate heat and convert visible light into far infrared light. This far infrared light develops or marks portions of the thermal layer which are adjacent the infrared layer.
