An ink jet recording head manufacturing method for manufacturing ink jet recording head having an ink passage, wherein a droplet of ink is ejected through the passage from an ink ejection outlet at an end of a passage onto a recording material. Ions are injected into a surface having the ink ejection outlet to change a surface property of the surface.

Ink jet head manufacturing method using ion machining and ink jet head

A process for producing a liquid jet recording head comprises the step of laminating a solid layer for formation of a liquid channel, a photosensitive material to be provided so as to cover over the solid layer, a discharge opening plate provided with a discharge opening communicated to the liquid channel in this order on a substrate; the step of irradiating an active energy ray in a pattern on the photosensitive material layer; and the step of removing the solid layer and the uncured portion of said photosensitive material layer corresponding to the pattern to form the liquid channel.
