ABSTRACT:
This invention provides a developing method for photosensitive materials, in particlar for a positive photosensitive lithographic printing plate, which enables an efficient development with minimum consumption of the developing liquid. The developing method of the present invention comprises the steps of: conducting a preparatory development by applying a developing liquid to an exposed photosensitive layer of a photosensitive material, the developing liquid being supplied in an amount of necessary for each developing cycle; removing the developing liquid; discarding the developing liquid; and again applying a developing liquid to the photosensitive material to complete the development.
