    摘要： The present invention aims to provide an ink which has a sufficiently large area factor even in a small ink droplet quantity and can obtain images having a high image density, and further has a superior storage stability. According to the present invention, a cyan ink is provided which is used in an ink set having four kinds of aqueous inks consisting of a cyan ink, a magenta ink, a yellow ink and a black ink in which each ink comprises at least water, a water-insoluble coloring material, and a plurality of water-soluble organic solvents having a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material, wherein, the ratio B1/A1 is from 0.5 or more to 3.0 or less, where A1 denotes the total content (mass %) of the good medium based on the total mass of the cyan ink and B1 denotes the total content (mass %) of the poor medium based on the total mass of the cyan ink, and a water-soluble organic solvent which shows the maximum Ka value among the respective Ka values of the plurality of water-soluble organic solvents as determined by the Bristow method is the poor medium.

    摘要： An ink set is provided which can prevent the occurrence of a new color mixing phenomenon in which a different ink comes into the insides of particular ink channels. The ink set is constituted of plurality of inks. The plurality of inks constituting the ink set is stored respectively in ink cartridges each having an ink storage portion which is brought into a hermetically-closed state. The difference in specific gravity between a first ink having the largest specific gravity and a second ink having the smallest specific gravity among the inks constituting the ink set is less than 0.020.
