PROBLEM TO BE SOLVED: To provide an image forming material from which plural sheets of color-proofs are easily and rapidly manufactured by providing the surface of a base with a photoresponsive tacky adhesiveness changing layer which has electrical conductivity and is changed in tacky adhesiveness by photoirradiation. SOLUTION: The image forming material 100 has the photoresponsive tacky adhesiveness changing layer 101 which is changed in tacky adhesiveness by photoirradiation and has the electrical conductivity on the base 102. When the image forming material 100 18 given with image-like light, the exposed parts (hatching part) lose the tacky adhesiveness (b). Next, insulative resin particles 104 are adhered thereto (c). Electrification is then applied to the particles to form the particles 105 having, for example, negative charges (d). The direct adhesion of the particles 105 having, for example, the negative charges is equally well. The colored particles 106 electrified reverse from the particles 105 are then adhered (e) and finally the colored particles 106 are transferred to a paper 103, by which the negative image is obtd. (f). The photoresponsive tacky adhesiveness changing layer 101 contains at least a compd. having an ethylenically unsatd. bond and a photopolymn. initiator. |
