PROBLEM TO BE SOLVED: To provide a damper device capable of suppressing deposition of particles of ink even at flowing speed of the ink lower than ever.SOLUTION: A sub tank 20 for supplying a recording head with ink supplied from a main tank, while reducing pressure variation, in which an ink reserving chamber 20a for reserving ink is formed, comprises: a filter 21 for passing the ink, while suppressing the passing of particles of ink when the particles of ink deposit; an ink introduction portion 22 for introducing externally supplied ink to the ink reserving chamber 20a; and an ink discharge portion 23 for discharging the ink in the ink reserving chamber 20a to the outside. The filter 21 sections the ink reserving chamber 20a into an introduction-side reserving chamber 20b communicated with the ink introduction portion 22 and a discharge-side reserving chamber 20c communicated with the ink discharge portion 23. The discharge-side reserving chamber 20c is arranged above the introduction-side reserving chamber 20b in the vertical direction. |
