PROBLEM TO BE SOLVED: To shorten time for filling a liquid into a region from a sub tank to a recording head under an initial state of a recording apparatus. SOLUTION: In an inkjet recording apparatus, under a condition that a driving mechanism 30 closes a feeding valve 3 to stop an ink flow path, a suction pump 31 continuously forms a negative pressure in the recording head 1, and the suction pump 31 continuously forms the negative pressure in the recording head 1. In addition, in parallel to this, under a condition that the driving mechanism 30 opens an atmosphere communicating valve 9, ink is fed to the sub tank 4 from a main tank 5. In addition, the driving mechanism 30 opens the feeding valve 3 to feed the ink to the recording head 1 from the sub tank 4. COPYRIGHT: (C)2010,JPO&INPIT |
