ABSTRACT:
Disclosed is a method for regenerating an ink recording medium formed by successively laminating an anisotropic electrically conductive layer, a heating resistor layer for generating heat in response to application of an electric signal, an electrically conductive layer, an ink parting layer, and a heat-melting ink layer, in which the heat-melting ink layer after print-recording with the ink recording medium is regenerated by use of ink particles containing a binding resin and a coloring agent, the improvement is in that by use of the ink recording medium further including an ink parting layer having a thickness of 0.08 to 3 .mu.m, and a volume resistivity of 10.sup.8 .OMEGA. cm or more, the heat-melting ink layer after print-recording with the ink recording medium is electrified with the same polarity as the potential of electrified ink particles, and then the ink particles carried by an ink carrier is deposited on traces of transferred ink formed in the heat-melting ink layer. According to the method, therefore, ink particles can be prevented from depositing onto an untransferred portion of the heat-melting ink layer of the ink recording medium, so that a difference in ink layer thickness between the ink transferred portion (traces of transferred ink) and the untransferred portion can be reduced to thereby make it possible to obtain good printed images even in the case of repeated use for a long term.
