PROBLEM TO BE SOLVED: To provide a recording material having high optical density, excellent image fixability, and excellent long-term storage stability and ejection characteristic stability, and image formation using the recording material. Is to provide a way. The recording material comprises a colorless or pale solution containing an electrolyte, a surfactant, a water-soluble organic solvent and water, and an ink containing a pigment, an anionic compound, a water-soluble organic solvent and water. The number of particles of 0.5 μm or more present in 1 liter of the material is 1 × 10 11 or more, and the number of particles of 5 μm or more is 1 × 10 9 or more. An image is formed by recording using the recording material by a thermal ink jet recording method. |
