  • Patent number: 5805949
    Abstract: A photosensitive material processing apparatus in which a pair of rollers respectively having water absorbing surface layers is disposed downstream of a washing processing section and the rotating shafts of said rollers are urged in the directions in which said rollers approach each other, wherein the thickness of said water absorbing surface layer of at least one roller of said rollers gradually decreases toward end portions of the at least one roller. In this way, since the thickness of the water absorbing surface layer of the at least one roller gradually decreases toward the end portions of said at least one roller, a gap is prevented from occurring between said water absorbing surface layer and said photosensitive material at the central portions of the rollers due to the flexing of the rollers.
