An ink jet recording ink comprising water, a coloring material, a water-soluble organic solvent and a plurality of dispersants each having a different HLB, and an ink jet recording method using this ink jet recording ink are disclosed. Preferably, given that respective HLBs of n (n>/=2) kinds of dispersants are such that HLB1<HLB2< . . . <HLBn, at least two dispersants satisfy the following formula:1</=HLBx-HLBx-1</=30(wherein, X is an integer from 2 to n). The ink jet recording ink and ink jet recording method of the present invention do not clog a nozzle, have an excellent dispersion stability, discharge responsiveness and discharge stability, and provide uniform images having high resolution and high optical density stably.
