An inkjet recording method comprising: shooting to a recording medium an active-light-ray-curable inkjet ink including a photopolymerizable compound, a wax, a photopolymerization initiator, and a coloring material, and that undergoes reversible sol-gel phase transition relative to temperature; and curing the ink by irradiating an active light ray to the ink that has been shot to the recording medium, wherein the ink including a (meta) acrylate compound (B) having a molecular weight of 300-1500 and a ClogP value within the range 4.0 to 7.0, the wax content being 1.0-10 percent by mass of the total mass of the ink, and the temperature of the recording medium at active light ray irradiation being set such that the saturation solubility of the wax with respect to the ink constitutes 0.5 percent by mass or less. According to this image-forming method, blooming is suppressed.
