PROBLEM TO BE SOLVED: To realize the stabilization of an ink flow and the facilitation of the discharge of air bubbles while achieving the miniaturization of an apparatus by efficiently integrating a damper action chamber for absorbing the pressure fluctuation of the ink in an inkjet printer apparatus. SOLUTION: A damper device 10 is provided with a damper action chamber 31a having a damper action surface at one side and formed flatly along its damper action surface and having an ink inflow port 53a connected from an ink supply source side and an ink discharge port 42a connected to a recording head 21 side. In this damper action chamber 31a, the ink inflow port 53a and an ink discharge port 42 are arranged at an approximate diagonal position in the damper action chamber 31a. A flexible film 32 is fixed so as to cover the lower surface opening of the damper action chamber 31a, and the flexible film 32 is used as a damper action surface. Two ribs 54 are formed on the ceiling surface of the damper action chamber, and the flow of the ink from the ink inflow port 53a to the ink discharge port 42 is guided.
