PROBLEM TO BE SOLVED: To provide a liquid delivering apparatus capable of suppressing the poor delivery of liquid caused by an abrupt change in the pressure of the liquid in a head. SOLUTION: The liquid delivering apparatus includes: the head 64 for delivering a filled ink; and a feeding pump 120 for pressurizing the liquid and feeding it to the head 64 through a feeding flow path 128A. The apparatus increases the pressure of the ink in the feeding flow path 128A when the pressure of the ink in the feeding flow path 128A is lowered to a vacuum threshold or lower, and reduces the pressure of the ink in the feeding flow path 128A when the pressure of the ink in the feeding flow path 128A is elevated to a pressurizing threshold or higher.
