There is provided an ink jet recording method for recording an image on a recording medium with an aqueous ink and an aqueous reaction liquid containing a reactant that reacts with the aqueous ink. The aqueous ink contains a pigment dispersed by the action of a carboxylic acid group, a resin particle and a water-soluble organic solvent. The rate of increase in the particle size of the pigment dispersed by the action of the carboxylic acid group when the pigment comes into contact with the aqueous reaction liquid is 8.0 times or more. The amount of water absorbed by the recording medium from the start of contact to 30 msecin a Bristow method is 10 mL/mor less.
