Abstract
An aqueous ink composition contains an organic solvent, a surfactant, and resin fine particles. The resin of the resin fine particles takes 500 minutes or more to melt at 40° C. with the surfactant, which is a temperature relatively close to the temperature the ink jet head is heated to by the platen or the like during recording. Such an aqueous ink composition exhibits a good filling property and can be continuously ejected stably.
