Abstract

An ink jet recording apparatus includes a recording head having discharging ports which discharge a recording liquid, a capping device capable of being mounted on the recording head, a pressure device which enables the recording liquid to flow under pressure in the ink supply passages to the recording head, and pressurizes the interior of the recording head when the capping device is mounted. A first ink supply tube to conductively connect the pressure device and the recording head, a second ink supply tube conductively connects the recording head and a recording liquid reservoir container; a conductive tube conductively connects the first ink supply tube and the second ink supply tube, and a controller controls the flow in the conductive tube, hence making it possible to remove air bubbles in the ink supply systems and ink passages easily and effectively by providing a conductive tube for a conventional ink supply systems.
