An inkjet recording method contains the sequential steps of: applying an aqueous pre-coat composition to a substrate, or applying and drying the aqueous pre-coat composition to the substrate; and subsequently applying and drying an aqueous ink composition. The aqueous pre-coat composition contains at least an aggregating agent. The aqueous ink composition contains at least a pigment, a polymer dispersant, and resin fine particles. The aggregating agent is selected from a pyrolytic cation resin, an organic acid, or a multivalent metal salt. A neutralizer for the polymer dispersant is selected from an organic amine. In the step of drying the aqueous ink composition, a temperature at which the aqueous ink composition is dried is set to be equal to or higher than a pyrolytic temperature of the aggregating agent.

A dye ink composition includes: a compound A represented by the general formula (I-1-1) or (I-1-2) as defined herein; a compound B represented by the general formula (1-2-1) or (I-2-2) as defined herein; at least one of a compound C-I represented by the general formula (I-3-1-1) or (I-3-1-2) as defined herein or a compound C-II represented by the general formula (I-3-2-1) or (I-3-2-2) as defined herein; a compound D represented by the general formula (I-4-1) or (I-4-2) as defined herein; and water, in which, as defined herein, a ratio of W.sub.1 to W.sub.A1 is 6.0% to 35.0% by mass, a ratio of W.sub.2 to W.sub.A1 is 20.0% to 45.0% by mass, a ratio of W.sub.3 to W.sub.A1 is 15.0% to 45.0% by mass, and a ratio of W.sub.4 to W.sub.A1 is 1.0% to 30.0% by mass.

Provided is an image forming method including: applying an ink to a print medium and heating the print medium to which the ink is applied at a heating temperature of 60 degrees C. or higher. The ink contains pigment-encapsulating resin particles comprising a pigment and a resin encapsulating the pigment. A proportion of the pigment alone exposed without being encapsulated with the resin is 10% by mass or less relative to solid components contained in the ink. Amass ratio of the pigment to the resin in the pigment-encapsulating resin particles is 0.25 or greater but 1.0 or less. A contact angle θm (°) of the ink when the ink is dropped by 5 microliters onto a print medium at 73 degrees C. is 25° or less.
