PURPOSE:To make dot modulation easy, make a high picture quality possible, and an easy treatment for clogging at an injection port possible by a method wherein to an ink mist which generates at an ink mist generating unit, a flow is given, and by applying a sound pressure to the ink mist which is floating in the air, the ink mist is jetted from a jet port. CONSTITUTION:At an ink mist generator 1, to an ink which is fed from an ink tank 6 through a liquid surface control valve 8, a sound vibration is given from the bottom to a vibration film, and the ink in the vicinity of the liquid surface is made to float in the air under a mist state. The formed ink mist is taken out from an ink tube 2, flows while drawn by a fan 10, enters an ink mist chamber 3, is collected by a filter 11, and is returned to the ink tank 6 from an ink collecting tube 12. When receiving a printing signal, a sound horn 9 of a sound vibration generator 4 sends a radiation pressure to the ink mist flow, then, the ink mist flows out from a jetting port 5 and is transferred on a recording paper 13 to perform printing. |
