ABSTRACT:
The invention provides a photosensitive material processing apparatus having a processing part consisting of a plurality of processing tanks for processing a photosensitive and a drying part, disposed downstream of the processing part in a processing sequence, for drying the material. The drying part includes infrared drying system and hot air current drying system. There are provided a distinguishing circuit and a controlling circuit. The distinguishing circuit distinguishs the condition of the material either on a constant-drying-rate condition or on a decreasing-drying-rate condition on the basis of physical characteristics of the material. The controlling circuit controls the drying part so as to use the infrared drying system on the constant-drying-rate-condition or to use the hot air current drying system on the decreasing-drying-rate-condition on the basis of a distinguishing result of the distinguishing circuit.
