Abstract

A thermal inkjet printhead. The inkjet printhead includes a heater that heats an ink in an ink chamber to generate a bubble, conductors to supply an electric current to the heater, and a bubble separation wall protuberantly formed on the heater to protect the heater by inducing an extermination position of a bubble when the bubble generated by the heater shrinks and dissipates.
