Liquid ejection head and method of production thereof

摘要

Without being dependent on design changes, a liquid ejection head and a method of production thereof are provided in which when time-division driving, liquid drop landing deviance in the direction of printing is capable of being corrected. In order to achieve this, before performing an exposure in order to form an ejection port, after forming a cavity that is shifted with respect to the location at which the ejection port is formed, exposure is performed.

主权项

1. A liquid ejection head for printing while moving relatively to a print medium in a movement direction, comprising:
a substrate having an energy generating element for generating energy that is used for ejecting liquid; and a photosensitive resin member which is formed on the substrate and which has arc-shaped cavities formed on one surface and ejection ports for ejecting liquid, the ejection ports being formed inside the cavities, wherein the ejection ports include a first ejection port formed inside a first cavity and a second ejection port formed inside a second cavity, and an opening center of the first ejection port is behind a deepest portion of the first cavity relative to the movement direction, and an opening center of the second ejection port is ahead of a deepest portion of the second cavity relative to the movement direction, when viewed from a direction perpendicular to the substrate.
