An ink jet recording apparatus which effects nonimpact recording by the application of a jet of ink to a recording medium while the amount of ink to be jetted towards the recording medium is controlled to render it proportional to the recording velocity. For this purpose, the ink jet recording apparatus is provided with a feed-back loop system through which an electrical signal indicative of the pressure acting on the ink within an ink tank is fed back to a comparator to control operation of a compressed air source from which the pressure is applied to compensate for reduction in static pressure of the ink within the ink tank resulting from consumption of the ink. For maintaining the amount of the ink jetted proportional to the recording velocity, various arrangements are disclosed.
