いる。2. Description of the Related Art Conventionally, there are various electrothermal transfer recording systems in which an electric signal corresponding to an image signal is applied to an ink medium provided with an anisotropic conductive layer and a heating resistance layer to transfer the ink onto the recording medium. Japanese Patent Laid-Open Nos. 56-10479, 60-259485, and Japanese Patent Laid-Open No. 11-113276 disclose that a powder ink is deposited on an electrically conductive thermal transfer recording medium and heat-melted. , A method of printing and recording using an ink medium having a leveled ink layer is disclosed. Also, JP-A-63-29708
Japanese Unexamined Patent Publication No. 4 (1994) describes a print recording method in which powder ink is uniformly adhered to an electrothermal transfer recording medium by electrostatic force and transferred to a recording sheet according to an image signal.

という欠点を有していた。However, none of the conventional electro-thermal transfer recording media used so far is sufficient. For example, when the ceramics described in Japanese Patent Laid-Open No. 63-84982 is used as a heating element, the flexibility is poor, and when the film thickness required for an electrothermal transfer recording medium is used, it is easily broken by bending. . Further, in the case of Japanese Patent Application Laid-Open No. 2-164592, there is a drawback that uniform and fine image quality cannot be repeated due to deformation due to heat due to energization and head pressing when printing and recording many times. .

で、圧接は十分に行うことが必要である。When conducting thermal transfer recording by the above-mentioned print recording apparatus, the thermal transfer recording medium is conveyed in the direction of the arrow by driving the ink medium conveying roll 11. On the powder ink holding layer of the electric heat transfer recording medium,
The powder ink 22 is supplied by the powder ink reproducing device to form a powder ink layer, and the powder ink is conveyed to the recording unit. In the recording section, an electric signal corresponding to the image is applied to the energized thermal transfer recording medium in a state where the stylus head is in pressure contact with the surface of the electric resistance film. As a result, the electric resistance film generates heat in response to the electric signal, and melts the powder ink in the powder ink layer. Since the powder ink layer is conveyed while being in pressure contact with the recording medium, the melted powder ink is transferred to the recording medium and a transfer image is formed on the recording medium. In addition, when the electrothermal transfer recording medium having the powder ink layer and the recording medium are not pressure-contacted to each other, the melted powder ink layer becomes thinner than the unmelted powder ink layer, so that the contact with the recording medium is made. However, since the transfer failure occurs, it is necessary to sufficiently perform the pressure contact.

る。In the present invention, since the powder ink peeling layer has the above-mentioned constitution, when the powder ink is supplied in the powder ink layer reproducing apparatus, the powder ink is
After the transfer, that is, the portion where the powder ink holding layer is exposed in the print missing portion is attached. In that case, the second or more layers of powder ink do not adhere because they do not come into contact with the electric resistance film or the powder ink holding layer, so that they adhere almost uniformly to one layer, that is, the thickness of the particle diameter of the powder ink. In the present invention, the powder ink adhered to the electric resistance film or the powder ink holding layer does not need to be heat-treated to be leveled, and can be stably adhered in a state of almost one layer. .
