(54) Image recording method and apparatus using the same


(57) Powder ink (Ip) is heated and vaporized by a heating apparatus (2). The vaporized ink (Ipg) is charged by a charging electrode (3) and attracted toward a recording medium (RM) by a back electrode (5). An electric field shutter (4) controls passage of the gaseous ink (Ipg) through an ejection hole in accordance with an output signal of a control unit (6), and the gaseous ink (Ipg) is intermittently ejected to the recording medium (RM) in accordance with an electric signal corresponding to an image data to be recorded. As a result, the ink (Ipg) is efficiently utilized and running cost is reduced.
