Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a printing method of a thermosensitive lithographic printing plate improving ink smudges without impairing inking property and printing durability. SOLUTION: The printing method of the thermosensitive lithographic printing plate includes heating an image forming layer of the lithographic printing plate having the image forming layer containing at least thermoplastic resin and a water soluble polymer compound on a water resistant support, for an image to form an image part, then applying a plate surface treating liquid containing inorganic particles and at least one kind of a compound (A) or (B) indicated below, to the plate surface before the start of printing, and then carrying out printing: (A) polyvalent metal salt, and (B) a water soluble compound having two or more cationic functional groups in the same molecule.
