Abstract
Provided is a method for inkjet image formation using a line head and an activating light beam-curing type ink, characterized in that the duration from the time, from a first ink lands on a recording medium, to the time that the first ink or a second ink of the same color series as the first color lands on the recording medium, is 25 ms or longer; the ink includes a gelling agent in an amount of 0.5-3.0 mass % to the entire mass of the ink; and the complex viscosity of the ink at the temperature at which the ink lands on the recording medium is 50-300 Pa·s. According to this method, even when an inkjet image is formed at high speed using ink that experiences a sol-gel phase transition, an image free from white spots and gloss differences in the overlap areas can be formed.
