Abstract
Disclosed is an image forming process employing a light-sensitive image forming material. The image forming material comprises a support, a light-heat conversion layer and an image forming layer, superposed in order. The process comprises the steps of imagewise exposing the image forming material to light so as to increase a bonding strength between the light-heat conversion layer and the image forming layer in the exposed area, pressing a receiving sheet on the light-heat conversion layer, and removing the receiving sheet from the image forming material to form a negative image on the receiving sheet in the unexposed area and to leave a positive image on the light-heat conversion layer in the exposed area. Otherwise, the process comprises the steps of imagewise exposing the image forming material to light so as to decrease a bonding strength between the conversion layer and the image forming layer in the exposed area, pressing a receiving sheet on the conversion layer, and removing the receiving sheet from the image forming material to form a positive image on the receiving sheet in the exposed area and to leave a negative image on the conversion layer in the unexposed area.
