ABSTRACT:
A direct drawing type lithographic printing plate precursor comprising a water-resistant support and an image receiving layer provided thereon, wherein a surface of the water-resistant support has the Bekk smoothness in the range of from 900 to 3,000 (second/10 cc) and the image receiving layer contains zinc oxide, a binder resin and a water-soluble organic compound having at least one acidic group selected from --CO.sub.2 H, --SO.sub.3 H and --PO.sub.3 H.sub.2, which is capable of forming a chelate compound with zinc oxide or a zinc ion. The direct drawing type lithographic printing plate precursor provides a lithographic printing plate which produces prints having a clear image without stains even when it is subjected to electrostatic transfer of a toner image formed by an electrophotographic copying machine.
