Abstract

PURPOSE:To suppress a change in the performance of a prescribed photosensitive material during continuous processing and to form a high-contrast image with few black spots by processing the photosensitive material in the presence of a specified compd. CONSTITUTION:A photosensitive material contg. two kinds of singly dispersed silver halide emulsions and a hydrazine compd. is developed in the presence of a compd. represented by formula I. This compd. is previously incorporated into the photosensitive material or added to a developing soln. used. The average particle size of each of the emulsions is <=0.5mum and the difference between the average particles sizes of the emulsions is >=0.1mum. In the formula I, each of L1-L4 is bivalent hydrocarbon, each of J1 and J2 is -O-, -COO-, etc., Y is H, a bivalent bonding radical, etc., Z is a heterocyclic ring, G is sulfonic acid, carboxyl, etc., and each of (k)-(r) is a prescribed integer. The compd. represented by the formula I may be a compd. represented by formula II and the hydrazine compd. may be a compd. represented by formula III.
