Abstract
An electric ink transfer recording method for obtaining a recorded matter which comprises putting a sheet to be recorded and an ink sheet generating Joule's heat when electrified and having a thermo-melting ink layer together; applying electricity to said ink sheet by contacting a return circuit electrode with the ink sheet and a recording electrode needle (stylus) with the surface of the ink sheet and impressing pulse voltage thereupon; and transferring the ink from the ink sheet to the sheet to be recorded, characterized in that an insulating liquid is interposed between the ink sheet and the recording electrode needle when obtaining the recorded matter.
