ABSTRACT:
A recording method performs recording on a recording medium using a pigment ink and a reaction liquid that has a higher surface tension than that of the pigment ink and contains a polyvalent metal salt capable of agglomerating the pigment ink. The method includes the steps of applying the reaction liquid on the recording medium, and bringing the pigment ink into contact with a surface of the reaction liquid that is present on the recording medium so that a filmy agglomerate, composed of an agglomeration of pigment aggregates produced by contact between the reaction liquid and the pigment ink, is formed on the surface of the reaction liquid applied on the recording medium. The pigment aggregates migrate on the surface of the reaction liquid toward a boundary between the reaction liquid and the recording medium, and by the migration of the pigment aggregates, an agglomeration of the pigment aggregates is formed along the surface of the reaction liquid, and thereby the filmy agglomerate is formed on the surface of the reaction liquid.
