Ink jet recording head, fabrication method thereof, and printer with ink jet recording head

摘要

A method of fabricating an ink jet recording head includes forming a photosensitive resin layer on a substrate having formed thereon an energy generation device for generating energy for ejecting recording droplets; pattern-wise exposing the photosensitive resin layer to an active radiation to a portion of the photosensitive resin layer where formation of a pattern of an ink fluid path is desired; laminating a top plate on the photosensitive resin layer; and eluting the pattern exposed portion of the photosensitive resin layer to form a pattern of an ink fluid path. An ink jet recording head includes a substrate a substrate; an energy generation device provided on the substrate and for generating energy for ejecting recording droplets; an exposed photosensitive resin layer provided on the substrate, the resin layer comprising a heat-crosslinking positive type resist material, and being provided with an ink fluid path defined between the substrate and the exposed photosensitive resin layer; a top plate laminated on the exposed photosensitive layer, the top plate being provided with an ink supply port communicating with the ink fluid path; and the ink fluid path ending as an ink ejection port on a side opposite to a side of the ink supply port. An ink jet recording apparatus includes a portion for mounting such an ink jet recording head.
