Abstract
An ink jet recording method includes heating a recording medium, and attaching an aqueous ink composition to the heated recording medium by ejecting the aqueous ink composition through a nozzle. The aqueous ink composition contains water, a solvent, and resin particles. In the attaching step, a temperature difference between a temperature of the nozzle and a surface temperature of the heated recording medium is −4 to 8° C. The resin particles include particular resin particles formed from a resin whose decrease rate of absorbance of light having a wavelength of 400 nm is 15% or smaller in 1 hour at 40° C. and 10% or larger in 1 hour at 80° C. in a liquid mixture containing the solvent contained in the aqueous ink composition and the particular resin particles such that a resin solid component of the liquid mixture is 0.5% by mass.
