Abstract: An inkjet printhead and a manufacturing method thereof. The inkjet printhead includes a substrate, a substantially cylindrical ink chamber storing ink and formed in an upper portion of the substrate, and a manifold supplying ink to the ink chamber in a bottom portion of the substrate, a channel-forming layer disposed between the ink chamber and the manifold and having an ink channel communicating between the ink chamber and the manifold, a nozzle plate stacked on the substrate and having a nozzle at a location corresponding to the central part of the ink chamber, a heater formed to surround the nozzle of the nozzle plate, and electrodes electrically connected to the heater to supply current to the heater. Therefore, the quantity of ink stored in an ink chamber can be increased. Also, when bubbles grow, the cylindrical ink chamber confines an ink flow area to ink ejectors, thereby reducing a back flow of the ink. Further, the quantity of ink supplied to the ink chamber can be adjusted by varying the number of ink channels formed in the channel-forming layer, thereby improving frequency characteristics of the inkjet printhead.

Abstract: 잉크 공급 장치 및 이를 구비하는 잉크젯 화상형성장치에 대해서 개시된다. 개시된 잉크 공급 장치 및 이를 구비하는 잉크젯 화상형성장치는: 잉크 저장부; 잉크 저장부로부터 잉크 통로를 통해 유입된 잉크를 인쇄매체에 분사하여 화상을 인쇄하는 프린트 헤드; 및 잉크 저장부의 일측에 구비되며, 잉크 저장부에 저장된 잉크 중 기체 성분이 제거되도록 초음파를 발생시켜, 기체 성분을 잉크 저장부의 빈 공간으로 분리하는 초음파 발생기;를 포함하는 것을 특징으로 한다.
본 발명은 종래 발명과 달리 종래 발명과 달리 잉크를 가열하지 않고 초음파를 이용하여 잉크 내의 기체 성분을 분리하므로, 잉크의 온도가 상승되지 않으므로 잉크의 물성이 변하지 않는다. 또한, 본 발명은 잉크가 기체 투과 튜브를 통과하면서 잉크 중의 기체 성분이 외부로 제거되므로 상기 기포가 다시 잉크에 흡수되는 것을 방지할 수 있다. 즉, 본 발명은 잉크에 용존된 기포와 기체 성분을 제거함으로써, 잉크 액적 분사시의 분사 불량을 방지할 수 있고, 이로 인해 인쇄 품질을 향상시킬 수 있다.
