Provided is an ink treatment solution set including: an ink composition that is water-based ink jet ink containing a coloring material; and a treatment solution that contains a coagulant, is ejected from an ink jet head, and is used for recording, in which any one of the ink composition and the treatment solution has a dynamic surface tension of greater than 32.0 mN/m and less than 36.0 mN/m at 10 ms and has a difference of equal to or greater than 6.0 mN/m and equal to or less than 10.0 mN/m between the dynamic surface tension at 10 ms and a dynamic surface tension at 1000 ms, an other one of the ink composition and the treatment solution has a dynamic surface tension of greater than 34.5 mN/m and less than 36.5 mN/m at 10 ms and has a difference of equal to or greater than 8.0 mN/m and equal to or less than 10.0 mN/m between the dynamic surface tension at 10 ms and a dynamic surface tension at 1000 ms, and the ink treatment solution set is used for recording on a poorly absorbable recording medium.
