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. The regenerated developing or peeling solution can be used again and again for the development or peeling.
