ABSTRACT:
In an apparatus comprising a plurality of processing compartments partitioned in a tank and each filled with a processing solution, a photosensitive material is successively passed through the compartments whereby the photosensitive material is processed by contact with the solution in each compartment. An outlet for discharging the solution is provided at a location other than the first and last compartments, usually at an intermediate compartment. A plurality of inlets for respectively supplying processing solutions having different functions can be provided at different locations so that the apparatus accomplishes two or more functions in a single tank. The apparatus becomes compact and the amount of processing solution replenished is reduced. A steady processing ability is maintained when the first compartment has a smaller volume than the remaining compartments and the solution is replenished to the system in a feedback control mode on the basis of a detected value representative of the amount of the solution supplied.
