Provided is an ink jet recording method including recording an image on a recording medium through use of an ink jet recording apparatus, the inkjet recording apparatus including: an aqueous ink; a recording head including an ink flow path in which the aqueous ink flows and including an ejection orifice configured to eject the aqueous ink; and a recovery mechanism configured to recover an ejection state of the aqueous ink from the ejection orifice by applying a pressure to the ink flow path inside the recording head. The aqueous ink contains resin particles each dyed with a basic dye exhibiting fluorescence and a water-soluble resin. The resin particles are each formed of a resin having an anionic group-containing unit. The water-soluble resin has an anionic group-containing unit.
