摘要： A bubble-jet type ink-jet printhead, a manufacturing method thereof and a method of ejecting ink, wherein, in the printhead, a manifold supplying ink, a hemispherical ink chamber, and an ink channel for connecting the manifold with the ink chamber are integrally formed on the substrate. A nozzle plate on the substrate having a nozzle, and a heater formed in an annular shape and centered around the nozzle are integrated without a complex process such as bonding. Thus, this simplifies the manufacturing process and facilitates high volume production. Furthermore, according to the ink ejection method, a doughnut-shaped bubble is formed to eject ink, thereby preventing a back flow of ink as well as formation of satellite droplets that may degrade image resolution.
