PROBLEM TO BE SOLVED: To provide a liquid jetting head, a liquid jetting apparatus, and a method of maintaining the liquid jetting apparatus which suppress a wasteful ink consumption, and clean an ink flow path to record high quality print.SOLUTION: The liquid jetting head is equipped with: a pressure chamber 31 for storing a liquid; a nozzle 17 jetting a liquid by communicating with the pressure chamber 31; a supply path 70 for supplying a liquid by communicating with the pressure chamber 31; a first supply path 71 for supplying a first liquid by communicating with the other end 70a of the supply path 70; a second supply path 72 for supplying a second liquid having a higher wettability than the first liquid by communicating with the other end 70a of the supply path 70; a first valve 61 for opening and closing the first supply path 71; and a second valve 62 for opening and closing the second supply path 72. After the second liquid is sucked from the nozzle 17 in the state of the first valve 61 being closed and the second valve 62 being opened, the first liquid is sucked from the nozzle 17 in the state of the first valve 61 being opened and the second valve 62 being closed. |
