Apparatus for processing photosensitive material

In an apparatus for processing photosensitive material, the apparatus having, a narrow processing chamber formed by a pair of substantially planar guide plates spaced apart a predetermined distance. The processing chamber having an entrance and an exit for allowing the photosensitive material to travel through the processing chamber. A first fluid supply is provided for supplying processing fluid to the processing chamber to create a first fluid layer on one side of the photosensitive material, and a second fluid supply is provided for supplying processing fluid to the processing chamber to create a second fluid layer on the opposite side of the photosensitive material. A plurality of spaced raised projection are disposed on the surface of the guide plates. The projections extend in a substantially perpendicular direction with respect to the direction of travel of the photosensitive material and across substantially the entire width of the photosensitive material.
