Abstract
The invention provides an image forming method having a step of applying an ink containing a coloring material to a recording medium by an ink jet recording system and a step of applying a reaction liquid which reacts with the ink to the recording medium, in which the ink is brought into contact with the reaction liquid on the recording medium, thereby forming an image, wherein the reaction liquid contains an oil and fat component having an iodine value of 100 or more.
Claims12
An image forming method comprising:
- a step of applying a water-based ink containing a coloring material to a recording medium by an ink jet recording system, wherein a solid content of the ink is 5% by mass or more and 10% by mass or less;
- and
- a step of applying a reaction liquid to the recording medium on which the ink is applied, the reaction liquid reacting with the ink,
- wherein the ink is brought into contact with the reaction liquid on the recording medium, thereby forming an image, and wherein the reaction liquid contains water and an oil and fat component having an iodine value of 100 or more,
- wherein an amount of the oil and fat component is 0.05% by mass or more and 10.00% by mass or less based on the total mass of the reaction liquid, and
- wherein the ratio of an application amount of the reaction liquid to an application amount of the ink is from ½ to 1/10.
