Abstract

An electromagnetic inkjet printhead for performing a printing operation with unheated ink not heated up improves the image quality. The electromagnetic ink-jet printhead includes a conductive vibration plate formed on one side of an ink chamber of a substrate. A pair of electrodes is formed on both sides of the conductive vibration plate so that an electric current is applied with the electrodes. A magnet is formed on the side of the conductive vibration plate.
