| 发明名称 | Ink-jet recording apparatus | ||
| 摘要 | 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 from the nozzle orifices and the nozzle surface; and an actuating mechanism including a pressing member that presses the absorbing member and the nozzle surface relative to each other with a force of 50 to 500 gf. 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. The absorbing member contains an impregnation liquid during the cleaning operation. | ||

| 主权项 | 1. An ink-jet recording apparatus comprising: 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 from the nozzle orifices and the nozzle surface; and an actuating mechanism including a pressing member that presses the absorbing member and the nozzle surface relative to each other with a force of 50 to 500 gf, wherein 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, the absorbing member has an area density of 0.005 to 0.15 g/cm2 and contains an impregnation liquid during the cleaning operation, and the inorganic pigment has an average particle size of 200 nm or more. | ||
