摘要： A method for cleaning the surface (ejection surface) of an ink jet head provided with an ink ejection opening by supplying a head liquid to the ejection surface and performing wiping operation. In the method, ink residue on the ejection surface is removed efficiently and surely, thus sufficient cleaning is performed. Application and stirring/mixing of the head liquid are carried out efficiently by performing first wiping operation such that the body portion of a wiper (9A) slides on the ejection surface while bending the wiper significantly. Mixture of the head liquid and the ink residue is then scraped efficiently by performing second wiping operation such that an edge portion at the forward end of a wiper (9B) slides on that surface.

摘要： This invention provides an ink for an ink jet recording method in which an ink is ejected from a recording head through the action of thermal energy. This ink can improve ejection stability and further can realize high storage stability and color developing properties. The ink is characterized in that the ink contains a pigment represented by general formula (1), a dispersant, a water-soluble organic compound, and a coagulation inhibiting substance capable of inhibiting coagulation after dispersion and breaking of the pigment and the content (% by mass) of the coagulation inhibiting substance based on the total mass of the ink is not less than 0.4 time and less than 1.3 times the content (% by mass) of the pigment based on the total mass of the ink.

摘要： A liquid for head fed to efficiently eliminate any ink residue, etc. adhering to the surface of inkjet head furnished with a discharge orifice for discharging a colorant-containing ink. When a nonvolatile solvent, such as glycerol, is used as the liquid for head, the nonvolatile solvent due to moisture absorption exhibits an extremely large mass change, thereby causing the amount of liquid fed to disperse. As for this problem, it has been found that reduction of mass change as compared with that in the moisture absorption in the nonvolatile solvent alone can be realized by premixing water in the nonvolatile solvent. Thus, a mixture of nonvolatile solvent and water made at appropriate given ratio is used as the liquid for head.

摘要： A method for cleaning the surface (ejection surface) of an inkjet head provided with an ink ejection opening, in which the cleaning is made by supplying head liquid to the ejection surface and performing wiping operation. In the method, the relative relationship of surface tension between the ejection surface, ink, and the head liquid is appropriately determined and an ink residue is efficiently and reliably removed from the ejection surface to achieve sufficient cleanliness. When the head liquid is supplied to the ink residue on the ejection surface, they are mixed and the ink residue is taken into the head liquid. Because both the ink and the head liquid used have higher surface tension than the ejection surface, wetness of the dissolved ink residue on the ejection surface is reduced and the dissolved ink residue is smoothly moved by wiping operation.
