抗シートに対する接触条件が大きく異なる。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric transfer recording device and an electric transfer recording method, and more particularly to an electric transfer recording device and an electric transfer recording method that can realize high-speed, high-sensitivity, and high-quality images. However, the conventional technology is the current transfer recording method (i.e., a plurality of recording electrodes are brought into contact with a recording sheet equipped with a resistance layer, and a recording voltage corresponding to the recording signal is applied between the recording electrodes, thereby increasing the resistance under the recording electrodes. A recording method that generates Joule heat in the layer and uses this heat to color the heat-sensitive layer, or melts or sublimates ink and transfers it to recording paper to obtain an image. A full-color image is created using an electric dye transfer method C that uses an ink sheet (hereinafter referred to as a resistance sheet) on which an ink layer containing a sublimable dye is provided, an image receptor with a dyed layer on its surface, and an electric head. The current-carrying head ζ used in this current-carrying dye transfer method is suitable for realizing high-speed printing. Deamo Mata
A board with multiple electrodes arranged to face each other in a one-to-one correspondence The bottom structure is also conductive so that voltages of the same polarity are applied with a common electrode.For example, as shown in Figure 3, the conductive A plate-shaped common electrode C forming one pole and a plurality of needle-shaped selection electrodes S1 to S6 forming the other pole are arranged in parallel on the surface of C) R made of a magnetic substance to correspond to the printed pattern. It is configured to conduct electricity to the selection electrode and the common electrode, and from the selection electrode S2 toward the common electrode C,
Current flows along the path shown by the arrow in the figure, and the heat generated in this area causes the heat-sensitive layer to develop color, or the ink to be melted or sublimated and transferred to the recording paper. When performing high-speed gradation recording using sublimable dye as a coloring material to obtain high-quality images, the recording energy is higher than ζ.Conventional current-carrying heads have the following problems.a Resistance sheet insertion side The contact conditions with respect to the resistive sheet are significantly different between the electrode on the side and the electrode on the sending side.

実施例
以下本発明の一実施例の通電転写記録装置及び通電転写
記録方法について、図面を参照しながら説明する。In other words, the electrode on the insertion side always contacts the unused part of the resistance sheet 4-4. The electrode on the exit side must come into contact with the part of the resistor sheet that has been thermally damaged due to the generation of large Joule heat between the opposing electrodes.However, with a conventional current-carrying head, the output is not possible. The contact area of the side electrode is not large enough, resulting in poor contact between the sending side electrode and the resistance sheet.
There was a problem that the image quality deteriorated significantly and that it could not withstand continuous recording.Also, it is known that when a resistor sheet is energized, the electrode with a higher potential is damaged. When the other electrode is repeatedly energized, it will change color.
This also means that the contact resistance increases.In the case of conventional current-carrying heads, if we compare the electrode with a higher potential to which recording voltage is frequently applied to the electrode that is not frequently applied, the degree of damage caused by current-carrying differs. , even if the contact resistance is different, i.e., the inter-electrode resistance value is large when driving a heavily damaged electrode, and the inter-electrode resistance value is small when driving a lightly damaged electrode, and the inter-electrode resistance values vary from one another. . Due to this variation, there was a problem that density unevenness occurred during recording.The present invention takes into consideration the above-mentioned problem.The contact of the electrodes on the resistance sheet delivery side is stable, and the variation in the resistance value between the electrodes is small.
That is, the present invention provides a current transfer recording device and a current transfer recording method that can realize high-speed, high-sensitivity, and high-quality images. an electrically conductive head that performs recording by bringing the separation electrode and the common electrode into contact with a resistance layer, the head comprising an insulating support that supports the separation electrode and the common electrode in opposition; The common electrode is arranged on the insertion side of the resistance layer, and the common electrode is arranged on the output side of the resistance layer. The current transfer recording method is characterized in that the potential of the common electrode is lower than that of the common electrode. This stabilizes the contact of the electrode on the sending side of the resistance sheet, which originally has poor contact conditions, and allows good contact with the resistance sheet to be obtained. By doing so, it is possible to reduce damage to the electrodes due to energization and to make the contact resistance uniform on the common electrode.
EMBODIMENT OF THE INVENTION A current transfer recording apparatus and a current transfer recording method according to an embodiment of the present invention will be described below with reference to the drawings.

When observed with a microscope, is the surface of the separation electrode 11 in good condition? Q,
-X The surface of the return electrode 12 suffered very little and uniform damage from energization, and no factors that would cause image quality deterioration or density unevenness were observed. Although the configuration is such that the return electrode 12 is formed on the support 14 and the return electrode 12 is formed on the insulating support 15, the configuration of the energizing electrode 1 is not limited to this (the separation electrode 11 is formed on the insulating support 13).
or the common electrode 12 formed on the insulating support 14
L% L-shaped plate that can be formed on top
With the configuration shown in the embodiment, the pressure from the platen 4 can be sufficiently applied, so that the contact between the recording electrode 11 and the common electrode 12 with respect to the resistance sheet is particularly good. Electrode materials are not limited to those made of chromium and nickel. Although alloys can be used, considering arc resistance, it is desirable that the melting point of the electrode material be 900°C or higher.Furthermore, in order to reduce high temperature oxidation, S
It is also effective to add i or A1.For the insulating supports 13, 14, and 15, ceramic-containing glass materials with a small friction coefficient and high wear resistance can be used, and boron nitride can be used. Aluminum nitride Alumina, mica glass ceramic containing crystallized glass Kaolin, talc, etc. can be used. However, in consideration of heat storage in the current-carrying head, it is desirable to use a material with high thermal conductivity for the insulating support 15. The resistive sheet 21 may also be a resistive film formed by mixing conductive particles such as carbon into a heat-resistant resin. Even if a film-forming resin such as polyetherketone is used, these resistive films are good if the thickness is about 4 to 15 g and the surface resistance value is about 1 Ω/mm. The color material layer 22 can be used as long as it is formed of at least a sublimable dye and a binder resin. , further comprising an insulating support supporting the separation electrode and the common electrode so as to face each other, the current-carrying head performs recording by bringing the separation electrode and the common electrode into contact with a resistance layer, the separation electrode being connected to the resistance layer. The common electrode is placed on the output side of the resistive layer to stabilize the contact of the electrode on the output side of the resistive sheet, which originally has poor contact conditions. By performing recording using a current-carrying head, image deterioration due to poor contact does not occur even when continuous recording is performed. By setting the potential lower than that of the electrodes, there is no variation in resistance value between electrodes caused by differences in electrode damage due to energization, and there is less unevenness in concentration.
