ABSTRACT:
Image recording is achieved with the use of a cylindrical recording head in which ink is contained, a plurality of ink passage holes being formed on a circumferential surface thereof. The recording head includes a plurality of scanning electrodes and a plurality of signal electrodes to which an image signal is transmitted. A heating material is disposed around each of the ink passage holes in the area surrounded by the electrodes. In response to the image signal, a certain number of ink passage holes are heated by means of the selected heating materials to which electric current is supplied via the electrodes whereby ink of which viscosity is reduced under the effect of thus generated heat flows to the outside through the ink passage holes until it is transferred onto a recording medium.
