PURPOSE:To safely perform printing in large quantities and to simplify the structure of a recording apparatus by reacting the gas generated from ink at the time of the application of voltage with olefinic substance between electrodes to suppress the discharge of the gas. CONSTITUTION:In an ink image forming stage, when voltage is applied between an ink support roll 1 and a plate 4, ink 2 changes in its adhesive properties to be transferred to the plate 4 and, at the same time, the components in the ink generate electrochemical reaction to generate gas. When voltage is applied between a plate 3 having no adhesiveness to olefinic substance and the ink support roll 1, the water contained in the ink is subjected to electrolysis to generate hydrogen gas which is, in turn, diffused into air to generate the danger of explosion and poisoning. Herein, since the hydrogen gas is reacted with the olefinic substance, the gas is absorbed by the olefinic substance before scattered to the outside and the discharge of the gas can be prevented substantially and danger can be avoided. The olefinic substance is uniformly applied to the surface of the plate 4 by a porous roll 11 impregnated with the olefinic substance. |
