PURPOSE:To obviate the generation of fluctuations in the optical density of images by a heat transfer method by forming a 1st shell essentially consisting of a soft releasable material and a 2nd shell consisting of a conductive material on an internal nuclear particle. CONSTITUTION:The above ink is formed by forming the 1st shell essentially consisting of the soft releasable material (A) and the 2nd shell consisting of the conductive material (B) on the internal nuclear particle contg. a waxy compd. such as paraffin wax, resin, such as ethylene/vinyl acetate copolymer, and the conductive material, such as carbon black. The component A is preferably a material which has 60 to 180 deg.C softening point and is not compatible with the above-mentioned waxy compd., for which polyethylene, etc., are usable. Carbon black, etc., are usable for the component B. The external addition of the components A, B by a mechanochemical reaction, etc., is possible. |
