Abstract
An ink jet recording method includes the step of depositing a reaction solution and an ink composition onto a recording medium is disclosed. The ink composition used has a colorant, a resin emulsion and the like, and the reaction solution has a reactant reactive with the colorant and/or the resin emulsion and the like to produce an agglomerate, such as a polyvalent metal salt or a polyallylamine. The reaction solution and the ink composition each has a surface tension of less than 40 mN/m. A sodium polyoxyethylene alkyl ether sulfate, an anionic surfactant, is used in order to realize this surface tension.
