PROBLEM TO BE SOLVED: To provide a non-aqueous ink with which discharge stability is ensured by suppressing wettability of a nozzle plate while maintaining power saving, satellite suppression, and improved printing density, and with which amine odor is reduced.SOLUTION: A non-aqueous ink includes a color material, a non-aqueous solvent, a non-aqueous resin, and a water-soluble resin, in which the water-soluble resin includes a functional group formed by converting an amino group into urea. The water-soluble resin is an amino group-containing water-soluble resin in which the amino group is converted into urea. As the amino group-containing water-soluble resin, a basic polymer electrolyte such as polyethyleneimine (PEI), polyvinylamine, polyvinyl pyridine or the like, or a derivative thereof can be mentioned. |
