PURPOSE: A head of an inkjet printer is provided to efficiently discharge ink by preventing the ink from back flowing, to improve quality of a printer by preventing cross torque and to increase a life span of the inkjet printer head. CONSTITUTION: An inkjet printer head comprises plural ink chambers(260) mounted corresponding to both sides of an ink supplier(280); a first ink passage(271) crossly formed with the ink supplier; a second ink passage(272) crossly connected to the first ink passage while being arranged with the ink supplier in a row; a third ink passage(273) engaging a rear portion of the ink chamber and the second ink passage; and an ink guide unit(274) guiding inlet of the ink by being mounted on a connected unit between the ink supplier and the first ink passage. The ink filled in the ink supplier is let in the first ink passage through the ink guide unit. Then, the ink is filled with the ink chamber through the second and third ink passages. The second ink passage is operated as a buffer by receiving back flowing ink generated through pressure of a bubble while heating the ink.
