ABSTRACT:
An ink-jet printing method including the steps of applying an electrical energy to electrodes within a printer head; creating different-density electric fields between the electrodes; letting pigment particles of an ink migrate into high density one of the electric fields; and letting the migrating pigment particles be transferred onto print media for printing. The inventive ink-jet printing apparatus includes a plurality of electrodes electrically isolated from each other so as to create electric fields different in density within a plurality of nozzles; first supports having orifices and supporting the electrodes; a plurality of electrode layers supplying electrical energy and connecting the electrodes to each other; a second support formed between an ink storage vessel and the electrode layers, and supporting the electrode layers; and electrically-connecting means for furnishing electrical energy to the electrode layers.
