Ink jet recording apparatus.

摘要

An ink nozzle plate (14) has ink discharge ports (4) for discharging ink, and an air nozzle plate (2) has air discharge ports(1), facing the ink discharge ports (4), for discharging air to jet out the ink, and an electric source (22,24) produces electric field operating the ink of the ink discharge ports, thereby to prolong the ink meniscus, and the ink is jetted out from the air discharge ports by the air-flow and the electric field, and a heating means increases a temperature of the air nozzle plate,thereby stabilising the jetted ink volume.
