  • Patent number: 6917375
    Abstract: The present invention relates to image-formation on any selected kind of objective body. The characterizing features reside in such that, based upon fed image data, required images are formed on an image-transferable sheet acting for image carry-over service and in reliance on sublimation image transfer technique, and then, by the use of said sheet with said images thus formed thereon, the formed images thereon are transferringly applied on the objective body. By adopting the above measures, the objective body can be formed sharply and clearly with any desired images, irrespective of kind and configuration thereof, with such superior results of highly improved unity and solidability between the formed images and the objective body to be decorated with.

  • Patent number: 6312789
    Abstract: A recording sheet of the present invention comprises a substrate film, a receptor layer for retaining a toner image and a release layer for releasing the receptor layer from a fixing surface of a fixing means, the receptor layer and the release layer being disposed on at least one side of the substrate film in this order from a position of the substrate film, wherein the release layer contains a release agent having compatibility to toner and releasing ability to the fixing surface. A preferable release agent is wax, particularly wax having a polar group in its molecular structure, such as carnauba wax and candelilla wax. The recording sheet of the present invention can provide a high quality of the toner image with no occurrence of fusion to the fixing surface and cohesive failure of the receptor layer even when the thermal fixing is carried out with no oil supplied to the fixing surface of the fixing means.
