Abstract
A developing or peeling solution for developing or imagewisely peeling an alkali-type photosensitive film containing a suspension of released photosensitive film is regenerated by introducing one or more reagents and a gas for depositing the suspension in floating state and removing the floated deposit by a skimmer from the developing or peeling solution, while a part or whole of the resulting treated solution is taken out of the system.
