PURPOSE:To provide a recorded picture of excellent quality at a high speed by providing a part of a recording-liquid feeding system with a deaeration means for excluding the melted gas in the recording liquid so as to carry out the stable discharge of the recording liquid. CONSTITUTION:To a head member 1 where the recording is performed by making small ink drips to be discharged from a discharge orifice 5, is added an ink-supplying system composed of an ink-supplying tank 10 having deaeration function, a filter 11, a transfer pump 12 and an ink cooler 13. To the bottom part of the ink- supplying tank 10 is fitted with a heater 10a, while inside of the tank 10 being provided with a temperature detector 10b for detecting the temperature of ink. The thermal information thereby detected is transmitted to an error amplifier 14 wherein a standard temperature is set beforehand and, based on the comparison between the transmitted and standard temperatures, the heater 10a is actuated to conduct automatic heating of ink. |
