Abstract
Provided are an ink jet ink set, an ink jet recording method, and an ink jet recording apparatus each of which can reduce the graininess of an image to be recorded and improve the water fastness of the image even in a recording medium such as plain paper. The ink jet ink set has a first ink and a second ink independently, and is used so that the first and second inks overlap each other at least partly upon application of the inks to a recording medium. The first ink contains at least a pigment and a silicone oil. The second ink contains at least a pigment and a graft polymer that includes at least a nonionic unit represented by the general formula (I) and a unit having a polysiloxane structure.
