PROBLEM TO BE SOLVED: To provide an ink feeder which can regulate the ink from flowing into a pressure adjusting means even when the ink is fed too much in a simple configuration. SOLUTION: A sub tank 120 has a hollow part in the inside thereof and is connected to a printer head 60 for discharging the liquid ink to perform desired printing and is composed so as to feed the liquid ink to the printer head 60. The above hollow part is connected to a liquid feed pump for feeding the liquid ink from a main tank in which the liquid ink is stored. After storing the supplied liquid ink temporarily, the hollow part is connected to an ink storage chamber 123 which feeds the ink to the printer head 60, to a float hold chamber 124 communicating with the side of the ink storage chamber 123 and to a pneumatic pump for adjusting pressure. In the sub tank, an insulation wall 124b is formed against the ink storage chamber 123, and an air chamber 124a communicating vertically with the upper edge of the float hold chamber 124 is provided.
