摘要： An object of the present invention is to provide an ink jet recording apparatus which can keep an adequate absorptivity of an ink absorbing member for a long period of time, even when such inks which react with each other are sucked through the same cap in a sucking recovery operation, by preventing a mixed ink collected by the ink absorbing member from thickening or being solidified. The ink jet recording apparatus has: a recovery unit 8 and 62 for draining ink from a black-ink discharge portion 13 for discharging black ink and a color-ink discharge portion 14 for discharging color ink which reacts with the black ink; an ink absorbing member 31 for collecting the ink which is drained by the recovery unit and separating the ink into a solid part 41 and a liquid part 42; and an ink introduction unit 7 for introducing the ink which is drained by the recovery unit, into the ink absorbing member.
