Abstract: 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 TH (° 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 TF (° C.), the aqueous ink containing a pigment and a polyester resin particle, a glass transition temperature TG (° C.) of the polyester resin particle, the temperature TH (° C.) and the temperature TF (° C.) satisfying relationships of the following expressions (1) to (3).

TG(° C.)>TH(° C.)  (1)

TF(° C.)≥TH(° C.)+10° C.  (2)

TF(° C.)≥TG(° C.)−10° C.  (3)

Abstract: The present invention provides an ink jet recording method capable of recording an image having good abrasion resistance by using an aqueous ink and a reaction liquid. In the ink jet recording method, the aqueous ink containing a resin particle and the reaction liquid containing a reactant for aggregating the component in the aqueous ink are ejected from a recording head of the ink jet system and applied onto a recording medium. The reaction liquid contains a compound represented by the general formula (1) (n in the formula represents an integer of 0 to 3). At least one of the aqueous ink and the reaction liquid contains a surfactant having an HLB value of ≤ 15.
