An object of the present invention is to provide an ink set capable of obtaining an image having excellent abrasion resistance when an image is formed on a recording medium by an ink jet recording apparatus as compared with a case where a treatment liquid containing an aggregating agent is not used. An ink for ink jet recording and a treatment liquid, the ink for ink jet recording contains at least a colorant, polymer particles, a surfactant, and water, and dynamic surface tension by a maximum bubble pressure method. , The dynamic surface tension after 1 msec is 32 mN / m or less, and the range of change in dynamic surface tension from 1 msec to 1 sec after is 0.2 mN / m to 3.0 mN / m The ink set, wherein the treatment liquid contains water and a flocculant.
