Abstract
The impact accuracy of ejected droplets, the quality of printed images, and print speed can be improved in a print head having an ink channel for which the width thereof in a direction orthogonal to an ink supply direction in which ink is supplied from an ink supply port to a pressure chamber is smaller than that of a pressure chamber. In the print head, the center of a heater along the ink supply direction is offset from the center of the pressure chamber along the ink supply direction, toward the side of the pressure chamber far from the ink supply port in the ink supply direction.
