Summary:PROBLEM TO BE SOLVED: To solve the problem that a quantity of ink passing a filter increases proportional to the elongation of a product life and impurities pile up in the filter in accordance with the lapse of use years to clog the filter and obstruct the circulation of the ink in many cases, whereby the ink cannot be normally supplied to a recording head, an image quality is deteriorated and eventually the recording head is broken in some cases because of null discharging of the ink. SOLUTION: The ink jet recording apparatus has the recording means for discharging the ink thereby recording to recording sheets, an ink-storing means for storing the ink to be supplied to the recording means, an ink-collecting means for collecting the ink discharged from ink discharge ports of the recording means and supplying the ink again to the ink-storing means, a viscosity reducing means for reducing a viscosity of the collected ink, a detachable foreign matter-removing means for removing foreign matters included in the collected ink, and a flowmeter for measuring a flow rate of the collected ink.
