Abstract
Provided is an ink including water, and an organic solvent, wherein a dried product of the ink has an endothermic peak temperature Tm of 22° C. or higher but 74° C. or lower as measured by differential scanning calorimetry, the differential scanning calorimetry includes first heating, cooling, and second heating, where the first heating is heating the dried product of the ink from −60° C. to 140° C. at a heating rate of 10° C./min, the cooling, which is performed after the first heating, is cooling a heated product obtained in the first heating from 140° C. to −60° C. at a cooling rate of −10° C./min, and the second heating, which is performed after the cooling, is heating a cooled product obtained in the cooling from −60° C. to 140° C. at a heating rate of 10° C./min, and the endothermic peak temperature Tm is an endothermic peak temperature in the second heating.
