PROBLEM TO BE SOLVED: To provide a liquid delivering device which is excellent in delivering reliability. SOLUTION: In the liquid delivering device, a pressure adjusting mechanism 17a for feeding ink to a delivering head 14 comprises a pressure chamber 240 which is an expanded flow channel relative to cylindrical flow channels 251 and 253, and a buffer section 61 communicating with the pressure chamber 240 via a communication channel 52. The buffer section 61 has its capacity variable according to internal pressure of the pressure chamber 240. Herein, suction is carried out from nozzles 45 of the delivering head 14 to contract the capacity of the buffer section 61 by a maintenance unit 25, and by virtue of an effect of venting of air in the pressure chamber 240 via a communication port 51, occurring when the contracted capacity is recovered, the ink filling ability of the pressure chamber 240 is enhanced.
