Abstract

Ink reservoirs are provided in a channel substrate correspondingly to various colors of ink. Two or more dummy nozzles which are not used for performing printing/recording are provided between printing/recording nozzles for jetting ink of different colors. A space wide enough to disposed therein at least two nozzles is provided between the dummy nozzles. Consequently, adjacent and different-color ink is not mixed, and nozzles having unstable operation and disposed near the side walls of the ink reservoirs are not used for performing printing/recording, so that images of high quality can be obtained.
