Provided is an image forming method excellent in reduction in color unevenness, optical density unevenness, bleeding, inter-color bleeding, a drying time, caused by the printing order; and an image forming apparatus excellent in adaptability to a higher speed. The image forming method and the image forming apparatus are characterized by use of an ink-set, wherein-an average value of rates of change over time in contact angle of the respective inks on plain paper is from 1.25 to 3.5 degrees/sec, a rate of change over time in contact angle of each ink on plain paper is less than 4.5 degrees/sec, a rate of change over time in contact angle of a mixed liquid of each ink and the liquid composition on plain paper is from 5 to 10 degrees/sec and the number of coarse particles each of 5 mum or more in diameter in the mixed liquid is 1x104 particles/muL or more.
