ABSTRACT:
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.
