Abstract
The present invention relates to a photographic processor and a method of processing photographic material where heat is applied to a processing drum in a manner which requires less warm up time and permits better film processing uniformity. The system of the present invention includes a circular drum and a heating material provided either on an outer surface of the drum, embedded into a side wall of the drum, or provided in an interior surface of the drum. The heating material is adapted to be heated so as to heat the processing path through which film is conveyed during processing, to an appropriate temperature for the processing of the photographic material.
