Abstract
A sealed ink jet assembly which is removable from an ink jet apparatus includes an ink jet head which has an ejection outlet found at a first surface of the ink jet head, an energy generating element for generating energy to eject ink through the ejection outlet, and an electric contact portion for supplying an electric signal from the ink jet apparatus to the energy generating element by mounting the electric contact portion to the ink jet apparatus. The electric contact portion is provided on the surface of the ink jet head which differs from the first surface, and an integral sealing member covers both the ink ejection outlet and the electric contact portion. The integral sealing member is removed when the assembly is mounted onto the ink jet apparatus.
