To provide an ink set for inkjet realizing improvement of image density and bleeding (feathering/ICB) by rapidly and sufficiently performing aggregation of coloring material, and to provide an ink tank for inkjet using the same, and to provide a method for inkjet recording and an inkjet recording device.
The invention relates to the ink set for inkjet comprising at least the coloring material, ions containing amphoteric ion substance and a treating liquid which has a liquid character (pH) different from the liquid character (pH) of the ink, and in using a coloring material which manifests an anionic character, the liquid character of the ink is basic and the liquid character of the treating liquid is acidic (the first invention). On the other hand in using a coloring material which manifests a cationic character, the liquid character of the ink is acidic and the liquid character of the treating liquid is basic (the second invention). And the invention relates to the ink tank for inkjet using the same and the method for inkjet recording and the inkjet recording method using the same.
