Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a processing method which raises the hydrophilic property of non-imaging part without spoiling oleophilic property of image silver and improves ink dirt of non-imaging part, in a processing method of lithographic printing plate using silver complex salt diffusion transfer process. SOLUTION: In processing method of a lithographic printing plate having physical development nuclei layer as an upper layer over silver halide emulsion layer formed on a support by using a silver salt diffusion transfer method, the processing method is characterized to use treatment liquid containing polyethylene imines having average molecular weight of 200 or more after development.
