Abstract
An ink set for ink jet includes a combination of a first ink and a second ink. The first ink contains a self-dispersible type carbon black and a specified particle A. The content of the particle A in the first ink is 0.05% by mass or more and 0.50% by mass or less, and the mass ratio of the content of the particle A to that of the self-dispersible pigment in the first ink is 0.056 times or more and 0.250 times or less. The second ink contains a specified particle B. The acid value a of the particle A and the acid value b of the particle B satisfy the relation of a≦b.
