Abstract: An ink jet recording method including, in the following order, a step of applying an ink containing a colorant and water onto an A surface which is one surface of a paper substrate by an ink jet recording system, a step of irradiating the A surface to which the ink has been applied with infrared rays having a maximal wavelength in a range of 800 nm to 3,000 nm, and a step of applying a post-treatment liquid containing water and a surfactant onto a B surface which is the other surface of the paper substrate, in which the paper substrate includes a pulp layer and a coating layer, the coating layer is disposed on an A surface side and a dry coating amount of the coating layer disposed on the A surface side is 15 g/m2 to 50 g/m2, and the coating layer is not disposed on a B surface side, or in a case where the coating layer is disposed on the B surface side, a dry coating amount of the coating layer disposed on the B surface side is 10 g/m2 or less.
