Described is an inkjet recording apparatus having an inkjet head (10) which comprises an ink supply port, a common ink cavity (8), a filter (51) having a plurality of filter channels (13a) communicating with the ink supply port at one end and the common ink cavity (8) at the other end, a plurality of ink ejection nozzles (4) each connected to the common ink cavity by a respective ink passage (6, 7), and a corresponding plurality of pressure generating means (5, 21) respectively associated with said ink passages, said pressure generating means (5, 21) being selectively drivable to eject ink droplets through the respective nozzles (4). The inertance (Mf) of said filter is one-fifth or less of the total inertance (Ma) of all ink passages and nozzles. A high reliable inkjet head for an inkjet recording apparatus enabling uniform ink ejection with no nozzle clogging and virtually no crosstalk is achieved. <IMAGE> |
