Abstract: A lithographic printing plate precursor is provided and has a porous aluminum support, (1) a layer containing a water-soluble polymer resin having a hydrophilic substituent adsorbable to a surface of the porous aluminum support and a sulfonic acid, and (2) an image recording layer from which unexposed areas can be removed by supplying an oil-based ink and an aqueous component thereonto on a printing machine without being subjected to development after exposure. The layer containing the water-soluble polymer resin, which has come in contact with the oil-based ink and the aqueous component, has a sulfonic acid group left therein.
