PROBLEM TO BE SOLVED: To provide a device capable of preventing the unevenness of printing density caused by the sedimentation of sedimentous components of an ink under the non-use condition for a long time for an ink-jet recorder using the ink containing sedimentous components. SOLUTION: An ink feeding-passage leading from an ink-tank feeding port to a delivery part H0001 is provided with a horizontal passage H0003 extending from the delivery part H0001 and a buffer section H0004 connecting to the ink-tank feeding port. The buffer section H0004 is located upstream the ink-feeding of the horizontal passage H0003, and a filter H0005 is installed and fixed further upstream the buffer. A first introductory tube H0011 is led from the lower part of the buffer section H0004 to the horizontal passage H0003, and a second introductory tube H0012 is led from the upper part of the buffer section H0004 to the horizontal passage H0003, and both the flow resistances of the first introductory tube H0011 and the second introductory tube H0012 are almost equal.
