POSITIVE IMAGE FORMING METHOD

摘要

PURPOSE:To form a positive image by using a heating means by subjecting a photosensitive material having an emulsion layer contg. uncoupled internal latent image type silver halide on a base to image exposure then to full-surface exposure under or after heating. CONSTITUTION:The silver halide emulsion layer contg. the silver halide photosensitive layer of which the surface is not preliminarily coupled is provide on the base to form a silver halide photosensitive material. Such a silver halide photosensitive material is subjected to image exposure then to full-surface exposure under or after heating by which the positive image is formed thereon. The max. density attained with the silver halide emulsion contg. the internal latent image type silver halide when developed by an internal type developing soln. is larger than the max. density attained when developed with a surface type developing soln.
