  • Patent number: 10195853
    Abstract: An ink jet recording apparatus includes a recording head having a plurality of nozzles through which an ink composition containing an inorganic pigment is ejected, a nozzle surface having nozzle orifices, and a liquid-repellent film disposed on the nozzle surface; an absorbing member that absorbs the ink composition containing the inorganic pigment from the nozzle orifices and the nozzle surface; and an actuating mechanism including a pressing member that presses the absorbing member, which contains an impregnation liquid, and the nozzle surface relative to each other. The actuating mechanism moves at least one of the absorbing member and the recording head relative to the other to perform a cleaning operation in which the ink composition is removed from the nozzle surface with the absorbing member.
