ABSTRACT:
In an ink jet recording apparatus, recording is performed by discharging ink through discharge ports in a recording head onto a recording medium. Ink flows into a housing from an ink storing portion through an ink inlet portion on an upper surface of the housing. The housing contains an impeller on an end of a shaft. An ink outlet portion of the housing is located tangentially with respect to the rotating impeller to supply ink to the recording head.
