ABSTRACT:
The present invention provides an ink set, an ink jet recording apparatus, an ink jet recording method, a recording unit, and an ink cartridge, which can produce ink jet color images in which the color balance does not easily become unstable even if the image is stored for a long time, and in which the color images have greater durability so that degradation of the visual appearance is not easily recognizable even if the image is stored for a long time. The ink set includes a first aqueous ink and a second aqueous ink having the same color tone, the second ink having a lower coloring material content than that of the first ink, and the degree of fading of an image produced with the second ink is the same as or lower than that of an image produced with the first ink.
