LIQUID EJECTION RECORDING HEAD AND LIQUID EJECTION RECORDER

摘要

PROBLEM TO BE SOLVED: To provide inexpensive and highly reliable ink jet recording head and recorder exhibiting an excellent recovery performance and a stabilized recording performance. SOLUTION: In order to supply ink stably from an ink supply member H1500 to a recording element substrate H1100, a first plate H1200 is provided with a tapered ink channel where the cross-sectional area decreases gradually from an ink supply opening H1201(K)-A on the recording element substrate H1100 side toward an ink supply opening H1201(K)-B of a channel forming member H1600, for example.
