A non-impact recording method and apparatus capable of printing with electroconductive thermal-transferable ink on a receiving surface, with uniform image density and high resolution, and with minimum energy consumption, by embodying the steps of superimposing on a receiving surface of a recording sheet an ink ribbon comprising an electroconductive thermal-transferable ink material; placing a recording electrode having a plurality of recording styli in contact with the ink ribbon, and a return electrode in contact with the ink ribbon, the return electrode disposed at a predetermined distance from the recording electrode, substantially parallel to the recording electrode, with the contact areas with the ink ribbon of the recording electrode being smaller than the contact area with the ink ribbon of the return electrode, which predetermined distance is in the range of 2xd</=Lm</=200xd, where d represents the diameter of each stylus of the recording electrode, and Lm represents the minimum distance between each recording stylus and the return electrode, with the total contact area with ink ribbon of the styli being one-fifth or less of the contact area with the ink ribbon of the return electrode; applying between selected recording styli and the return electrode image-delineating electric current so as to generate Joule's heat in the portions in the ink ribbon immediately below the recording electrode; and transferring the electroconductive thermal-transferable ink material from the ink ribbon to the receiving surface of the recording sheet.
