摘要： An ink cartridge includes an ink-jet head and plural liquid chambers storing inks different from each other. The minimum value A1 (g/ml) for the ink densities of the inks stored in the plural liquid chambers and the maximum value B1 (g/ml) for the ink densities of inks each obtained by evaporating 10 mass % of each of the inks stored in the plural liquid chambers satisfy the relationship of (B1−A1)/A1≦0.100. A stable image can be obtained, in which, even when the ink cartridge is stored for a long time period at the time of physical distribution, or is stored for a long time period in a state of being mounted on a recording apparatus so that the stored inks are brought into a situation in which the inks are apt to evaporate, a change in color balance is small as compared to an initial state.

摘要： There is provided a cyan ink for ink jet and an ink jet recording method using the same, which can reduce both reciprocating color uneven and beading without impairing fastness property even when a yellow ink or a magenta ink containing a specific coloring material with excellent fastness property is used. In the ink jet recording method using a yellow ink and a cyan ink, or a magenta ink and a cyan ink, the yellow ink and the magenta ink contain a specific coloring material and have a surface tension of 33.0 mN/m or more and 36.0 mN/m or less, and the cyan ink contains a specific phthalocyanine compound, contains 1,5-pentanediol as an organic solvent, and has a surface tension of 32.9 mN/m or more and 35.4 mN/m or less.
