<P>PROBLEM TO BE SOLVED: To provide an ink-circulation type inkjet recording apparatus capable of suppressing discharge failure of ink. <P>SOLUTION: A control part of the inkjet recording apparatus 1 performs a control to feed air from an air layer 42 to an air layer 32 with an air pump 7 while controlling an ink pump 6 to keep the volume of the air layer 32 of an upstream tank 3 larger than that of the air layer 42 of a downstream tank 4 in a sealed state from atmosphere pressure of the upstream tank 3 and the downstream tank 4 during circulation of the ink. <P>COPYRIGHT: (C)2012,JPO&INPIT |
