PROBLEM TO BE SOLVED: To provide a means of avoiding an irregular consistency of ink which is allowed to stand in an ink container for a long period of time appearing as the irregular consistency of a storage image. SOLUTION: The problem of an irregular consistency that generates a precipitation phenomenon of a pigment can be solved without adding a special construction to an exchange type ink tank which is a consumption member, since the ink flow in the ink tank can be generated and stirred by equipping a mutually circulating pump, etc. for mutually circulating through more than two communication openings in communication with the inside of an ink tank when providing the ink tank to the device body.
