Abstract:
A method of forming a multi-color image, which comprises,generating color separation images in at least two colors, said color separation images being formed by the use of colored toner powder;transferring said color separation images in successive image-transfer steps, under pressure, to an elastically deformable adhesive intermediate medium provided with a top layer to form a multi-color image;softening and transferring the multi-color powder image under pressure to a receiving support, wherein between two consecutive image transfer steps the powder image consisting of one or more color separation images is so deformed on the intermediate medium, under the influence of heat and/or pressure, that the powder image becomes adhesive for toner powder; andtransferring a subsequent color separation image, not only to the intermediate medium, but also to the powder image already present, wherein the intermediate medium comprises a heat-insulating layer in which the product of the thermal conductivity coefficient .lambda. in J/m sK, the density .rho. in kg/m.sup.3 and the specific heat C.sub.p in J/kg K has a value of less than 2.times.10.sup.5.
