ABSTRACT:
A method of producing an image comprising processing an imagewise exposed silver halide photosensitive material comprising a support having thereon a silver halide emulsion layer containing a silver halide sensitized with a selenium sensitizer in a black-and-white developer which contains a chelate complex salt of a transition metal. In a preferred embodiment, an electric current is passed through the developer to remove halide ions therefrom and to regenerate (reduce) the metal complex. A protective layer may be provided on the silver halide emulsion layer having a thickness of 0.6 .mu.m or less.
