Abstract: There is provided an inkjet head assembly. The inkjet head assembly includes an ink tank including a first storage part receiving ink, and a second storage part communicating with the first storage part through at least one through hole and maintaining a full ink level upon receiving ink from the first storage part, and an inkjet head connected to the second storage part by an ink supply path and ejecting ink upon receiving ink from the second storage part. The inkjet head assembly includes the ink tank supplying ink to the inkjet head and storing ink separately in the first storage part and the second storage part thereof, and the second storage part maintains a full ink level therein. Accordingly, deterioration in print quality can be minimized due to the second storage part attenuating pressure variations caused by ink movement when the inkjet assembly moves.
