PROBLEM TO BE SOLVED: To reduce waste of stored fluid and to shorten the tact time by means of a small device. SOLUTION: A printer 10 comprises an inkjet head 30 for ejecting ink to a sheet 20, a tube 32 for supplying ink to the inkjet head 30, an ink tank 36 connected with the tube 32 and storing ink supplied from the tube 32, a section 38 for containing the ink tank 36, a detector for detecting the volume of the ink tank 36, a regulator for regulating the negative pressure in a space between the ink tank 36 and the containing section 38, a pump connected with the regulator and generating negative pressure of a fixed level being used by the regulator for regulating the negative pressure in the space, and a CPU 70 for controlling the regulator such that the negative pressure in a space between the ink tank 36 and the containing section 38 corresponds to a volume detected by the detector.
