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.

Ink jet recording method and ink jet recording apparatus

The ink jet recording method includes ejecting an aqueous ink from a recording head to apply the aqueous ink to a recording medium, to thereby record an image. The ink jet recording method includes: ejecting the aqueous ink heated to a temperature T(° C.) from the recording head to apply the aqueous ink to the recording medium; and heating the recording medium having the aqueous ink applied thereto to a temperature T(° C.), the aqueous ink containing a pigment and a polyester resin particle, a glass transition temperature T(° C.) of the polyester resin particle, the temperature T(° C.) and the temperature T(° C.) satisfying relationships of the following expressions (1) to (3).(° C.)>(° C.)  (1)(° C.)≥(° C.)+10° C.  (2)(° C.)≥(° C.)−10° C.  (3)
