PURPOSE:To enhance printing quality by preventing the relative reduction of a recording dot size to resolving power at the time of the advance of ink consumption or at the time of draft mode recording and the change of the recording dot size due to the kind of recording paper in an ink jet recording apparatus equipped with a liquid level height control mechanism controlling the height of the liquid level of the ink in an ink reservoir supplying ink to a recording head. CONSTITUTION:A liquid level height control mechanism 11 detecting the lowering of the liquid level of the ink in an ink reservoir 2 supplying ink to a recording head and controlling the height of said liquid level corresponding to the detection result is provided. By this mechanism, the jet amount of the ink from the recording head is controlled to make it possible to control the size of the dot recorded on a recording medium. |
