ABSTRACT:
A photosensitive material processing apparatus includes a drying device for drying with drying air a photosensitive material processed with processing solutions; a waste-solution recovering section, having an absorbing material, for recovering waste solutions of the processing solutions discharged from a plurality of processing tanks due to the absorbing material being impregnated with the waste solutions; and a waste-solution drying device having a duct for introducing warm air from the drying device into the waste-solution recovering section and adapted to dry a recovered waste solution. Since the waste solution is dried by the waste-solution drying device after recovery of the waste solutions of the processing solutions, intervals of maintenance provided for the waste-solution recovering section are extended, and the operating efficiency in waste solution processing is improved.
