ABSTRACT:
A wet type direct image recording method an apparatus wherein an ink/image is formed directly on a surface treated recording material by passing the recording material between an image signal voltage applying electrode and an ink supplier device.
The surface of the ink supplier device has depressions in its surface layer, which permit capillarity of the ink, thereby the ink is held in the surface layer of the ink supplier device, and at least either of the ink and the surface layer of the ink supplier device is electrically conductive so that the ink or the ink supplier device serves as a counter electrode for the image signal voltage applying electrode.
The ink in the depressions is easily attracted electrostatically to the surface of the recording material when an electric field is formed between the image signal voltage applying electrode and the ink or the ink supplier device since the surface tension of the ink is reduced significantly by the electric field.
