ABSTRACT:
Provided is a method for making a lithographic printing plate in which the development is carryied out by coating a developer on a photosensitive element comprising a support and at least a silver halide emulsion layer and a physical development nuclei layer, characterized in that coating amount of the developer is 60 ml or less for 1 m.sup.2 of the photosensitive element, and the developer contains at least one thioether compound and at least one alkanolamine compound as silver halide solvents. The resulting lithographic printing plate is high in printing endurance and has no stains in non-image portions. Furthermore, the running development processing can be stably carried out.
