An image receiving sheet having a support sheet, an intermediate layer and an image receiving layer, wherein the intermediate layer comprises a polymer and a plasticizer having at least one ester bonds and molecular weight of 700 to 3,000. Otherwise, an image receiving sheet having a support sheet and an image receiving layer wherein the image receiving layer comprises a polymer and the plasticizer. A heat sensitive ink sheet has a heat sensitive ink layer which is formed of a heat sensitive ink material comprising colored pigment and thermoplastic resin such as amorphous organic polymer. An image forming method is conducted by using the heat sensitive ink sheet and one of the image receiving sheets by area gradation by the use of a thermal head or laser beam.

Image receiving sheet and image forming method

An image formation process uses two light-sensitive elements comprising first and second adhesive light-sensitive layers which become nonadhesive upon exposure to light, respectively, and first and second toner elements comprising toner layers (a') and (b') of hues (a) and (b), respectively. The process steps include: A) imagewise exposing the first light-sensitive layer; B) contacting the first light-sensitive layer with layer (a') in the first toner element; C) separating the first toner element and the first light-sensitive element, transferring the toner layer portion corresponding to the unexposed portion of the light-sensitive layer to the light-sensitive layer and leaving the toner layer portion corresponding to the exposed portion of the light-sensitive layer on the support for the first toner element; D) contacting the adhesive surface of an image receiving element with the surface of the toner layer of the first toner element on which the toner layer has been left corresponding to the exposed portion of the first light-sensitive layer; E) separating the image receiving element and the first toner element, transferring the toner layer to the image receiving element; F) repeating A) to C) with the second light-sensitive element and toner element, respectively; and G) contacting the surface of the transferred toner layer of the image receiving element on which the hue (a) toner layer has been transferred with the surface of the hue (b) toner layer and separating the image receiving element and the second toner element, transferring the hue (b) toner layer to the image receiving element.
