Abstract
An ink jet recording apparatus that records by causing ink to adhere to a recording medium includes a recording head with nozzles for ejecting ink and a cap member for covering and sealing the ink ejecting surface of the recording head and containing a porous body for retaining ink introduced into the cap member one of two ways, either by ejecting it from the nozzles or by using a suction pump communicating with the cap member. The recording apparatus has two storage modes, one of which is used for long-term storage, whereby a relatively large amount of ink is retained by the porous body, and the other of which is used for short-term storage, whereby a smaller amount of ink is retained by the porous body.
