Abstract
An apparatus for processing a silver halide photographic material having an emulsion surface, includes a supply device to supply processing solution from a container to the emulsion surface through a space; a converter to convert one of density level of an image signal and a light amount of a exposure signal into a processing signal representing an amount of the processing solution; a regulating device to regulate an amount of the processing solution in accordance with the processing signal so that the regulated amount of the processing solution is supplied to the emulsion surface of the silver halide photographic material through the space by the supply device.
