摘要：PROBLEM TO BE SOLVED: To provide a liquid jetting apparatus in which sedimentation of a pigment in a liquid at a holding part which stores the liquid can be suppressed, and a liquid circulating method. SOLUTION: The liquid jetting apparatus has a liquid jetting head 51 which jets the liquid that includes the pigment, a main tank 52 which stores the liquid supplied to the liquid jetting head 51, and a sub tank 53 which is prepared between the liquid jetting head 51 and the main tank 52 and stores the liquid. The liquid jetting apparatus has a first circulation pass 54 which circulates the liquid between the liquid jetting head 51 and the sub tank 53, and a second circulation pass 56 which circulates the liquid between the sub tank 53 and the main tank 52. The liquid jetting apparatus adopts such a constitution that a ratio of a flow rate of the second circulation pass 56 to a flow rate of the first circulation pass 54 is not smaller than a ratio of a liquid amount in the sub tank 53 to a liquid amount in the liquid jetting head 51.
