Abstract
Abstract An automatic image developing apparatus for automatically developing an image recorded on a photographic photosensitive material includes a feeder assembly for feeding the photographic photosensitive material successively to processing tanks for developing the image, fixing the developed image, and washing the photographic photosensitive material. The feeder assembly has at least one conduit for supplying cleaning water to remove processing solutions from the feeder assembly. The conduit has small holes or slits defined in its outer peripheral wall for ejecting cleaning water against guide plates and rollers of the feeder assembly.
