In a method of regenerating an ink image recording medium of a multilayered structure, after an ink image on the ink image recording medium is recorded, the surface of the heat-fusible ink layer of the ink image recording medium is uniformly charged. Then, a liquid ink for generating the ink layer, being placed under an electric field applied thereto, is supplied to the ink image recording medium. The liquid ink is prepared by dispersing heat-fusible ink powder into a liquid dispersion medium. As a result, the heat-fusible ink powder selectively sticks onto the portion on the ink release layer where the heat-fusible ink layer is absent because the ink was transferred. Finally, the ink image recording medium thus processsed is dried to remove the liquid dispersing medium.

An ink transfer medium, and a method for manufacturing the medium are provided. The ink transfer medium is of the electrically fusible type, and has an anisotropically electrically conductive layer characterized by greater electrical conductivity in the direction normal to the surface of the layer than in a direction parallel to the surface of the layer. Other layers, sequentially provided next to each other, include a resistive layer for converting an electrical signal into heat, a conductive layer, an ink separation layer, and a fusible ink layer. Examples are given illustrating the use of the ink transfer medium.

An image formed of a colored image forming material mainly composed of thermoplastic resin and carried by a paper sheet is heated and fused by a heating member which is typically belt-like and includes an adhesion preventive layer for preventing adhesion of the image forming material, a conductive layer formed on the adhesion preventive layer, and an electric heating layer for generating heat upon reception of electric energy. A power supply member typically has divisional electrodes arranged in the width direction of the heating member, and supplies the electric energy to the heating member. A pressurizing member is disposed opposite the heating member with the image-carrying sheet interposed therebetween, and provides a pressure acting between the divisional electrodes and the image-carrying sheet. A control circuit controls pulse currents to be supplied to the divisional electrodes through the power supply member in accordance with an image signal having been used for forming the image on the image carrying sheet.

A printing head comprising a plurality of printing electrodes positioned in parallel with each other on a surface of an electrically insulating board. Electrically conductive projections are provided in a zigzag format on the exposed portions of an electrically insulating layer of the electrically insulating board near the front edge of the plurality of printing electrodes. The electrically conductive projections are formed such that when they are projected onto a sliding surface by the printing head, the adjacent electrically conductive projections are positioned with a lateral separation distance of 50% or less of the electrically conductive projection width, or with an overlapping portion of 25% or less. Slits are provided between the printing electrodes on at least the front edge of the plurality of printing electrodes.
