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. The inorganic pigment is present in the ink composition in an amount of 20% by mass or less and has a Mohs hardness of 1.5 or more and an average particle size of 200 nm or more.
一种喷墨记录设备包括一个记录头,该记录头具有多个喷嘴,含有无机
颜料的墨
水成分通过这些喷嘴喷出;一个喷嘴表面,该喷嘴表面具有喷嘴孔,喷嘴表面上有一层斥液膜;一个吸收部件,该吸收部件从喷嘴孔和喷嘴表面吸收含有无机
颜料的墨
水成分;以及一个致动机构,该致动机构包括一个压紧部件,该压紧部件将含有浸渍液的吸收部件和喷嘴表面相对压紧。致动机构使吸收部件和记录头中的至少一个相对于另一个移动,以执行清洁操作,在该操作中,油墨成分与吸收部件一起从喷嘴表面去除。无机
