PURPOSE: To provide a processing device for a photosensitive planographic printing plate in which production of contamination is decreased in a water washing process in the processes of processing a photosensitive planographic printing plate, the amt. of waste washing water can be decreased, the maintainability is improved, and the cost for the processing device is decreased. CONSTITUTION: The processing device for a photosensitive planographic printing plate is equipped with at least a water washing device C for washing with water in a washing tank 20 in the poststage of a developing device B. In the washing tank 20, activated carbon is fixed with an alkali-resistant membrane 23, or the processing device for photosensitive planographic printing plate is equipped with at least a water washing device C for washing with water in a washing tank 20 in the poststage of a developing device. In this processing device, activated carbon is fixed to the water washing tank with an alkali- resistant film 23 and a fixing member. |
