A plate-making method of a lithographic printing plate precursor including an image forming layer and a support, includes: (a) a step of preparing a lithographic printing plate precursor containing, in the image forming layer, an infrared absorber, a polymerization initiator, a polymerizable compound, a hydrophobic binder polymer and a compound represented by the formula (1) or (2) as defined herein; (b) a step of imagewise exposing the lithographic printing plate precursor; and (C) a step of developing the exposed lithographic printing plate precursor with an aqueous solution containing at least one water-soluble polymer selected from the group consisting of gum arabic and starch with an automatic processor equipped with a rubbing member.
