Abstract
A method of forming a multi-color image, wherein color separation images are generated at least two colors, and color separation images are formed by the use of colored toner powder and are transferred, in successive image-transfer steps under the influence of pressure, to an elastically deformable adhesive intermediate medium provided with a top layer, where the color separation images are collected to form a multi-color image, the method comprising softening the multi-color powder image and transferring it 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, subsequently transferring the 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.
