PROBLEM TO BE SOLVED: To solve a problem that ink is not stably ejected from nozzle heads with being affected by other ink channels in a distribution tank.SOLUTION: The inkjet recording apparatus includes: a plurality of nozzle heads 10 for recording an object to be printed 1 with the ink; and an upstream tank 25 for supplying the ink supplied from a supply port 42 to the plurality of nozzle heads through a plurality of upstream ink channels 46 and 26. The upstream tank includes an upstream common ink chamber 41, to which the ink is supplied from the supply port and which communicates with the inlets of the plurality of upstream ink channels. The pressure losses in the plurality of upstream ink channels when the ink flows are equal to one another, and when, from the ink flowing direction in the inlet 44 of the upstream ink channels, the respective inlets are projected to a surface vertical to the ink flowing direction, the inlets, which are the closest at least in position of the inlets from each other, have respective positions deviated from each other in the ink flowing direction. |
