Apparatus for the wet processing of photographic sheet material
 An apparatus for the wet processing of photographic sheet material comprises at least one treatment vessel having a rotatable endless surface means biased towards a reaction member to define a nip there-between through which the sheet material path extends. At least one of the endless rotatable surface means and the reaction member comprises an inner region (58) of elastomeric material having a relatively low hardness, and an outer region (60) of elastomeric material having a relatively high hardness positioned over the inner region (58). Such a roller minimises carry-over between vessels without damage to the sheet material while being capable of successfully being used as a drive roller. The roller exhibits good stability against treatment liquids and has good processing qualities.
