A recording method includes the steps of: preparing a first ink composition containing a solvent, a coloring material and an anionic polymer, in which the coloring material is incorporated in the anionic polymer, and a second ink composition containing a solvent, a coloring material and a cationic polymer; and applying the first ink composition and the second ink composition onto a medium by bringing the compositions into contact with each other. The contact increases the viscosity of at least one of the anionic polymer and the cationic polymer.
