1. An ink jet printing method comprising:
a first step of ejecting an ink containing a water-soluble polymerizable component A and water from a printing head of an ink jet system to apply the ink to a medium M, to thereby form a first image; and
a second step of applying an active energy ray to the first image to form a second image,
wherein the polymerizable component A is dissolved in the first image,
wherein a moisture concentration “x” (mass %) in the first image and a moisture concentration “y” (mass %) in the second image placed under an environment at a humidity of 95% satisfy a relationship of 0<(y/x)≤0.80, and
wherein the polymerizable component A has a lower critical solution temperature in the water.
