ABSTRACT:
An improved cylindrical processing roller is provided for use in a motor driven photographic processing apparatus of the type which spreads a fluid processing composition in a thin, substantially uniform layer between selected layers of integral type self-processable film units while advancing a film unit to the exterior of a camera after photoexposure. The improvement in the roller resides in a novel circumferential roller surface roughened by electrical discharge machining techniques to provide the roller with a high-friction characteristic for transporting the film units while being insufficiently rough to leave any visually perceptible marks on a film unit.
