摘要： PROBLEM TO BE SOLVED: To enhance cleaning efficiency of a wiper when such a head as ejection became unstable due to coloring agent fixed to the nozzle surface portion is cleaned with the wiper by imparting processing liquid to the vicinity of a nozzle thereby dissolving or dispersing the coloring agent, and to prevent the nozzle from drying up easily when a recorder is stopped for a long term and the head is stored while being covered with a moisturing cap or a suction cap by ejecting the processing liquid into the cap.
SOLUTION: The ink jet recorder comprises a head having a nozzle which can dissolve or disperse the component in recording liquid and ejects processing liquid containing more preservative/mold preventive when water is a major component. When the processing liquid itself is sprayed previously to a paper, generation of mist due to electrostatic charge can be prevented even in case of an ink jet printer having a conveyor belt using an electrostatic attraction belt.

摘要： PROBLEM TO BE SOLVED: To provide an ink jet recording method which enables recording of a fine line having a high density (OD) and excellent coloring properties and causing little feathering and blurring, by the use of paper equivalent to plain paper, instead of an exclusive medium such as coated paper, which is extremely excellent in fixing properties, shows high reliability and makes it possible to conduct normal printing anytime and immediately, without employing particularly any complicated recovering device, which enables smooth and natural reproduction recording of a complicated Chinese character, slant line part or curved line part with ink of high safety and which enables, in addition, attainment of a recorded image having good resistances to water and light. SOLUTION: An ink-jet ink-recording medium set consists of the ink which contains a non-water-soluble coloring material, water being a medium for dispersing this material and a water-soluble organic solvent and wherein the concentration of the coloring material is 6-15 wt.%, and of the recording medium on the surface of which fibers containing an ionic compound for fixing the coloring material are exposed.

摘要： PROBLEM TO BE SOLVED: To provide an ink-jet printer which is adapted to make a color difference inconspicuous while it records at a high speed in two directions.
SOLUTION: An independent arrangement nozzle (K) and sequential arrangement nozzles (C, M and Y) are present at positions not in the same place when seen from a main scanning direction (that is, at positions where they do not overlap) (Fig. (A)). In contrast, the independent arrangement nozzle (K) and the sequential arrangement nozzles (C, M and Y) are arranged on the same main scanning line in a comparative example shown in Fig. (B). The number of nozzles arranged in a vertical scanning direction can be reduced by setting one color independently, and a vertical scanning direction length of a head can be shortened as a whole. The printer can be constructed more compact. Moreover, since the nozzles arranged independently and the nozzles arranged sequentially are not set to the same position in the vertical scanning direction, ink is prevented from overlapping, or the color difference is made inconspicuous as a whole owing to a variation of an overlapping sequence by a position of pixels.
