Abstract
An ink jet recording method for recording an image on a recording medium by ejecting an aqueous ink from a print head of an ink jet recording apparatus includes applying an aqueous ink onto a recording medium, and cleaning a liquid contact member coming into contact with the aqueous ink in the ink jet recording apparatus with an aqueous cleaning liquid. The cleaning liquid contains a surfactant, a first water-soluble organic solvent with a lower vapor pressure than water, a second water-soluble organic solvent with an SP value, measured by a Fedors method, of 9.8 or more to 14.2 or less, and a third water-soluble organic solvent with a water retention capacity of 50% or less in an amount by mass of 0.7 or more relative to the total amount by mass of the water-soluble organic solvents. The cleaning liquid has a pH of 8.5 or more.
