Summary:PROBLEM TO BE SOLVED: To provide an inexpensive image recording apparatus which exhibits less fluctuation in pressure in a nozzle part of an inkjet recording head by a simple constitution and is small-sized. SOLUTION: An ink circulation passage is formed by an inkjet head 51 for delivering ink from a nozzle, a first tank 47 for storing the ink to be fed to the inkjet head 51 and arranged at a higher position than the inkjet head 51 in the vertical direction, a second tank 73 for storing the ink which is not delivered by the inkjet head 51, and a pump 77 for circulating the ink between the first tank 47, the inkjet head 51 and the second tank 73. A pressure adjusting part 10 for adjusting the inner pressure in the ink circulation passage communicates with the second tank 73. COPYRIGHT: (C)2010,JPO&INPIT
