PURPOSE:To simplify the processing step and to eliminate or reduce labor by forming a printout image by image-wisely exposing, followed by applying an erasing solution to an unnecessary image part, and by supplying a developer which is substantially unused, to each photosensitive planographic plate to be treated, followed by developing said plate. CONSTITUTION:The exposed PS plate P is previously applied the erasing solution to the unnecessary image part, and carried in the direction of the arrow (a) by means of pair of the carrying rollers 1-3, 3'. The developer is supplied to the surface of the plate sent to the developing part on a guide plate 4 by pair of rollers 1, from developer pipes 5, 5'. At the same time, the surface of said plate is developed, while rubbing said surface by the rubbing members 6, 6' provided with a nylon brush as development promoting operation. Said developer is the substantially unused developer, and is stored in a developing tank 7, and supplied to the plate by a pump 8. Thus, the processing step is simplified, and the labor is eliminated or reduced, and the developing of the titled plate is stably carried out. |
