发明名称 Inkjet print head
摘要 The landing precision of ink drops is improved to improve the image quality and increase the printing speed. An inkjet print head ejects ink supplied from an ink supply port from a plurality of ejection ports respectively connecting to ink paths having different flow resistances by using energy generated by a plurality of electrothermal transducer elements respectively corresponding to the plurality of the ejection ports, wherein each of the plurality of the ejection ports connected to the ink paths having a low ink flow resistance is arranged so that the center of each of the plurality of the ejection ports is positioned farther away from the ink supply port to the center of the corresponding electrothermal transducer element than each of the plurality of the ejection ports connected to the ink paths having a high ink flow resistance.
