LIQUID JET RECORDING HEAD

摘要

A liquid jet recording head provided with a plurality of recording element substrates which jet black and color inks allows improvement of the qualities of a color-inked image without degrading those of a black-inked image. The liquid jet recording head is provided with a first recording element substrate provided with a first jet port for jetting a liquid, a second recording element substrate provided with a second jet port larger than the first jet port, and a support member which supports the first recording element substrate and the second recording element substrate by means of a plane.  The distance from the plane of the support member to the first jet port is longer than that from the plane of the support member to the second jet port.
