Abstract:
1. An ink jet recording method comprising: (i) supplying on a coated paper a treatment liquid containing 15% by mass or more of a polyvalent metal compound for fixing the components contained in an ink composition and having a viscosity at 25° C. of from 2 mPa·s to 8 mPa·s, in an amount of from −50% to +50% with respect to the value of ΔV [ml/m wherein in Formula (I), Vr represents a roughness index of the coated paper obtained from a measurement of liquid absorbability according to the Bristow method, and Vi represents the amount of transfer at an inflection point where the value of absorption coefficient of the coated paper changes in the measurement of liquid absorbability according to the Bristow method; (ii) recording an image by ejecting an ink composition containing a colorant, resin particles, a water-soluble organic solvent and water by an ink jet method on the coated paper to which the treatment liquid has been supplied; and (iii) carrying out at least one treatment selected from the group consisting of a drying treatment and a penetration treatment such that the amount of the treatment liquid on the coated paper after the at least one treatment is 0.20 ml/m
