Abstract

See full text

A roller of the type useable as either of the pair of pressure applying rollers used in an instant photographic camera wherein a film unit consisting of a photosensitive element, an image receiving element and a rupturable pod containing a processing fluid is passed between a pair of pressure applying rollers which apply compressive pressure to the film unit so as to rupture the pod and dispenses the processing fluid between and in contact with the photosensitive element and the image receiving element to initiate a diffusion transfer process. The roller has a round roller body having fine surface irregularities and a plated layer of nickel which is reduction separated on the surface of the roller by using the roller material as a catalyst. The plated layer separated on the surface of the roller is of uniform thickness. The roller may be heat hardened after the nickel layer is reduction separated.
