摘要： A pre-processing fluid composition includes nonionic resin particles, a water-soluble metal salt, and water. The nonionic resin particles contain a nonionic resin having a structure derived from an aromatic ring-containing polyester polyol. A glass transition temperature of the nonionic resin particles is -30° C. or higher but 10° C. or lower.
