PROBLEM TO BE SOLVED: To provide a damper device capable of improving the stability of performance in suppression of pressure fluctuations in ink supplied from a tank to a recording head.SOLUTION: In a damper device 20, a pressure chamber 20a communicating with a recording head, and a communication path 20e communicating a tank with the pressure chamber 20a are formed. The damper device comprises: a valve 23 for opening or closing the communication path 20e; a shaft member 26 for moving the valve 23 in a valve opening direction indicated by arrow 20g, which is the direction in which the valve 23 opens the path 20e by making contact with the valve 23; and a film member 30 which supports the shaft member 26 and moves the shaft member 26 in the valve opening direction indicated by arrow 20g by deforming due to the change of an amount of ink in the pressure chamber 20a. The film member 30 is provided with a plurality of annular tapers 31a which have the same center and are different from each other in easiness of deformation. |
