ABSTRACT:
Photographic material to be processed passes generally horizontally through a succession of processing chambers including a developing chamber. The latter includes a developing-fluid tank containing a body of developing fluid, the body of developing fluid having an upper surface. At least one rotatably mounted submerging roller causes transported photographic material to pass below the upper surface of the body of developing fluid. A counter-pressure roller presses the transported photographic material against the submerging roller during transport of the photographic material through the developing chamber. Flow elements are arranged to damp the agitation of the body of developing fluid resulting from rotation of the submerging and counterpressure rollers. The submerging and counterpressure rollers are so arranged that the trailing end of transported photographic material does not drag over the pheripheral surface of either roller in circumferential-surface contact therewith.
