Summary:PROBLEM TO BE SOLVED: To sustain a high image quality by enhancing the quality of reused ink. SOLUTION: Ink ejected from the ejection opening 13 of an ink jet recording head 1 is collected in an ink collecting tub 106 and sucked by means of a suction pump 2 to flow into an ink collecting passage 18. Pressure of the collected ink is measured by means of a sensor 7 before the ink passes through a filter 6. Measured pressure of ink in the ink collecting passage 18 is then expressed in terms of the flow rate of ink by means of a calculating unit 9. If the flow rate determined through measurement is lower than a first reference value as the use limit of the filter 6, i.e., a limit value of the flow rate of ink, the calculating unit 9 urges replacement of the filter 6 on an LED 17.
