Abstract
A bubble-jet type ink-jet printhead, includes a substrate, a nozzle plate, a wall, and a heater, wherein the heater is interposed between the substrate and the nozzle plate to divide an ink chamber into a main ink chamber and a secondary ink chamber, wherein a main bubble and a secondary bubble are generated. The printhead may further include an ink channel for introducing ink into the secondary ink chamber for supplying the ink to the main ink chamber. The printhead according to the present invention consumes less energy, prevents a backflow of ink, and operates at increased speed.
