摘要：
An image quality improvement treatment liquid is disclosed that improves quality of an image formed on a medium by reacting with color materials in ink and agglutinating the color materials upon contact with the ink including water and color materials to be ionized in water or color materials to be ionized in water due to absorption with components having ionic characteristics in water. The image quality improvement treatment liquid includes at least one of cationic components and components capable of acidizing water, at least one of nonionic surfactant and amphoteric surfactant as a foaming agent, and water-insoluble fatty acid.
