When an image is printed with inks each containing a polymer emulsion and a film forming agent, the ejection of the inks is controlled so that the ink having a relatively low dynamic surface tension forms dots having a higher dot connectivity than the dots formed with the ink having a relatively high dynamic surface tension.

An ink jet recording medium comprising a substrate and an ink receiving layer which is provided on at least one surface of the substrate and contains inorganic fine particles having an average secondary particle size of 1-4 &#x3bc;m as measured by a Coulter counter method in an amount of 0.2-2.0 g/min terms of solid content mass. The ink receiving layer satisfies the following conditions with respect to a pore distribution curve as determined by a nitrogen adsorption method: (1) total pore volume in a pore size range of 10-30 nm is 0.25 ml/g or more, (2) total pore volume in a pore size range of 30-70 nm is 0.1 ml/g or more, and (3) volume ratio of the total pore volume in the pore size range of 10-30 nm to the total pore volume in the pore size range of 30-70 nm is from 1:0.4 to 1:1.
