An ink jet recorder includes: a recording head; an ink cartridge detachably attached to the recording head; a purging device for purging the nozzle of the recording head; and a carriage for holding the recording head and conveying it across the width of a recording medium and an area outside the medium; and a controller. Provided in an area outside the medium is an ink receiver for receiving the ejection of ink for flushing. The controller controls the carriage with the recording head in such a manner that, before purging is started by the purging device, the carriage is moved to a position where the recording head opposes the ink receiver and then the recording head ejects ink for flushing. Air bubbles generated in the joint passage formed between the recording head and the ink cartridge when they are fitted to each other, can be displaced into the recording head by flushing, and the thus flushed air bubbles can be suctioned together with ink by purging.
