An ink jet recording apparatus supplying ink from a main tank to a head via a sub tank. The sub tank has two flow paths communicating with the main tank, an atmosphere communicating part, and a liquid exit part to the head. The liquid in the sub tank is maintained at a constant liquid level position by selecting, between the two flow paths, the flow path having a lower flow path resistance. Thus, the ink jet recording apparatus can store a predetermined amount of liquid stably in the sub tank. The ink jet recording apparatus and the liquid supply apparatus are capable, even when the main tank is detached or the ink therein is exhausted, of continuing the recording for a predetermined time or number of sheets, utilizing the ink in the sub tank. |
