ABSTRACT:
A method and apparatus for forming an image using an image forming sheet that is normally non-photosensitive but can be rendered photosensitive by preheating and is exposed at the preheated area to a light image to form therein a latent image and then heat-developed to form a visible image. After preheating, the preheated area is cooled by cooling means prior to exposure.
