An ink jet print head is provided which is highly reliable in recovering its performance by removing bubbles accumulated in the ink paths to reliably prevent print quality degradation in bi-directional printing. In the ink ejection member having an odd number of arrayed ink supply ports to supply ink to the ejection openings, the ink colors of the ink supply ports are arranged laterally symmetrically and a plurality of ink tanks are arranged side by side so that the direction of array of the ink supply ports is perpendicular to the direction of array of the ink tanks.
