1. An inkjet recording method, comprising:
applying a stimulus to a recording ink to allow the recording ink to jet to thereby record an image on a recording medium, wherein the recording medium comprises a support and a surface layer formed on at least one surface of the support, and has a transferred amount of pure water on a surface thereof at a side of the surface layer of 1 mL/m2 to 10 mL/m′ with contact duration of 100 ms as measured by a dynamic scanning absorptometer, wherein the recording medium is surface-modified with a corona discharge treatment or a plasma treatment, wherein the recording ink comprises a water-dispersible colorant, an organic solvent, a surfactant, a water-dispersible resin, and water, wherein the organic solvent comprises one or more polyhydric alcohols having an equilibrium moisture content of 30% by mass or higher at a temperature of 23° C. and relative humidity of 80%, an amide compound represented by the following General Formula (I), and at least one of compounds represented by the following General Formulae (II) to (IV), and wherein a total of a solid content of the water dispersible colorant and a solid content of the water dispersible resin is 8% by mass to 35% by mass, and a mass ratio (A/B) of the solid content of the water dispersible resin (A) to the solid content of the water dispersible colorant (B) is 2 to 8: where, R denotes a C4-C6 alkyl group; where R1 denotes a hydrogen atom or a C1-C2 alkyl group, and R2 denotes a C1-C4 alkyl group, where R3 denotes a hydrogen atom, a C1-C8 alkyl group, a cyclic alkyl group, or an aromatic ring, where R4 and R5 each denote a C1-C8 alkyl group. |
