Abstract
An image recording method is provided. The image recording method includes the steps of: applying a treatment liquid containing a pore forming material onto a recording medium to form a porous layer; and applying a metallic ink containing a metallic pigment onto the porous layer. A surface tension of the metallic ink at 23° C. is equal to or greater than a surface tension of the treatment liquid at 23° C. The surface tension of the metallic ink at 23° C. is 19 mN/m or more and 28 mN/m or less.
