    Abstract: An image recording method including sequentially applying first and second inks onto a recording medium transported at a transportation speed of 40-300 m/min and heating and drying the inks, in which in a case where a difference in landing time between the inks is defined as T1 seconds and a time from a time point at which a last liquid droplet of the second ink lands to a time point at which the liquid droplet is heated and dried is defined as T2 seconds, T1 is 0.020-1.2, and T2 is 2.0 or shorter, each of the inks contains water, an organic solvent, a surfactant, and wax particles, the organic solvent includes a solvent species A represented by Formula (1) or (2) and having a ClogP value of −0.60 to 2.70, and the surfactant includes an acetylene-based surfactant, a polyoxyethylene alkyl ether-based surfactant, and a polyether-modified silicone-based surfactant.

    Abstract: Provided is an image recording method including a step of preparing an ink containing water and a white pigment, and a step of jetting the ink from an ink jet head in a liquid droplet amount of 1.0 pL or greater to apply the ink onto a base material, in which in a case where an ink jetting surface of the ink jet head is immersed in the ink in a vertically standing state for 2 seconds, the jetting surface is pulled up from the ink in the state, and the jetting surface is allowed to stand in the state for 1 minute, a ratio of an area of a region to which the ink is adhered to an area of the jetting surface is 40% by area or less.

    Abstract: An image forming method includes a step of applying a pretreatment liquid containing an aggregating agent (D) and water (E) onto a base material and a step of forming an image by applying an ink containing water (A), a resin (B), and an organic solvent (C) satisfying Expression (1) onto the pretreatment liquid applied onto the base material, in which in a region to which the ink has been applied, CC which is the number of grams of the organic solvent (C) to be applied per area of 1 m2 and CD which is the number of grams of the aggregating agent (D) to be applied per area of 1 m2 satisfy Expression (2). SPB represents an SP value (MPa1/2) of a main resin in the resin (B), SPC represents an SP value (MPa1/2) of the organic solvent (C), and |SPC−SPB| represents an absolute value of a difference between SPC and SPB. |SPC−SPB|≤10.0  Expression (1) 0.10≤CC/CD≤2.90  Expression (2)
