    Abstract: A method of producing a lithographic printing plate comprising a step of providing on a support a layer has a hydrophobic surface and comprises an oxidizable material and a reducible material, a step of irradiating imagewise with active rays in the presence of a photocatalytic metal compound, wherein the oxidizable material in the irradiated area is decomposed imagewise to convert the layer surface in the irradiated area surface into hydrophilic property and form an imagewise distribution of hydrophilic areas and hydrophobic areas: and a lithographic printing plate precursor used in the aforesaid method. In accordance with this method, no development-processing is required for plate-making, the plate-making operations can be carried out as the plate precursor is mounted on a printing press, and the lithographic printing plate made can have an excellent press life and hardly generates staining.
