摘要:
An ink jet image-forming method for forming an image by applying an ink in a fixed amount of 0.5 pl or more to 6.0 pl or less to plain paper. The ink contains a self-dispersion pigment, water, a water-soluble compound having a coefficient of hydrophilicity-hydrophobicity of 0.37 or more as defined by the equation (A) stated in the description and a water-soluble compound having a coefficient of hydrophilicity-hydrophobicity of 0.25 or less, and has a surface tension of 34 mN/m or less. The application of the ink is divided into plural times when an image having a portion where the ink is applied in a duty of 80% or more and an amount of 5.0 μl/cm2 or less in total is formed in a basic matrix for forming the image, and the amount of the ink applied at each of the times divided is 0.7 μl/cm2 or less.
