Abstract:
A processing method of a lithographic printing plate precursor includes: exposing imagewise a lithographic printing plate precursor comprising a support on a surface of which at least one of: a hydrophilizing treatment; and an undercoat layer has been provided and an image-recording layer, to cure an exposed area of the image-recording layer; and undergoing developing processing with an aqueous solution having pH of from 2 to 10, wherein the aqueous solution comprises an amphoteric surfactant and an anionic surfactant selected from an anionic surfactant having an aliphatic chain and a total number of carbon atoms included in the aliphatic chain of 6 or more and an anionic surfactant having an aromatic ring and a total number of carbon atoms of 12 or more, and a content of the anionic surfactant is from 0.1 to 3.3% by weight of the aqueous solution.
