ABSTRACT:
An ink supply mechanism, which supplies ink from an ink container for storing ink to an ink jet recording unit which discharges ink, comprises a first filter member provided in an ink outlet section of the ink container; an ink supply passage which conductively connects the ink jet recording unit and the ink container for supplying ink from the ink container to the ink jet recording unit; and a second filter member provided in the ink supply passage between ink discharging ports of the recording unit and the first filter member. The second filter member is provided with holes which create the capillary force greater than the negative pressure in the ink container. With the above structure, it is possible to provide an ink jet recording apparatus capable of making the recovery amount compatible between a usual recording device and a recording device of a high-speed type, making a recording device of a high-speed type usable in a usual recording apparatus, and improving the ink usage efficiency in the recovery process.
