Abstract:
An ink jet recording apparatus for recording information on a recording medium by ejecting plural inks, the apparatus comprising:mounting means for mounting a recording head for ejecting plural inks and for scanning the recording head relative to the recording medium; andan ink reservoir for receiving the plural inks from an ink supply source through first supply paths and for storing the plural inks to be supplied to the recording head through second supply paths, said ink reservoir having:a pair of fluid path forming members joined at inner faces thereof, at least one of said inner faces having therein a plurality of elongated grooves to form plural fluid paths for the plural inks between said joined fluid path forming members, wherein said fluid paths communicate with a plurality of ports in one of said fluid path forming members, said plurality of ports being arranged in a scanning direction of said mounting means, anda fluid storage chamber forming member, having a plurality of concave portions, joined to said one of said fluid path forming members at an outer face thereof, said fluid storage chamber forming member being disposed so that said concave portions form with said outer face plural fluid storage chambers for the plural inks in communication with said plurality of ports, wherein said fluid paths comprise said first supply paths and suction paths for applying negative pressure to said fluid storage chambers, and said second supply paths extend through said pair of joined fluid path forming members.
