PURPOSE:To always develop a negative type and positive type photosensitive lithographic plate under a stable condition, by processing a photosensitive lithographic plate with a desensitizer immediately after developing the plate by supplying the same repeatedly used developing solution. CONSTITUTION:At the time of development a developing solution supplying pump 9 is driven and supplies a developing solution to a photosensitive lithographic plate through developing agent supplying nozzles 8. The liquid used for development process is squeezed by squeezing rollers 5 and returned to a developing solution storing tank 10, and then, circularly reused. A desensitizer processing section is composed principally of a desensitizer processing tank 2, carrying rollers 3, tandem rollers 6', squeezing rollers 5', and desensitizer supplying nozzles 8', and supplies a desensitizer which is circularly used by means of a pump 11 to the lithographic plate passed through a development processing section through the nozzles 8'. |
