摘要:
A recording head includes a plurality of nozzle arrays separately provided so as to correspond to kinds of recording liquids to be discharged, a plurality of common liquid chambers from which the recording liquids are supplied to the nozzle arrays, a plurality of recording-liquid introducing passages communicating with the common liquid chambers, and a plurality of filters provided in the recording-liquid introducing passages. Upstream aperture areas of the filters are equal to each other, and downstream aperture areas of the filters are different according to the kinds of recording liquids passing through the filters.
