PURPOSE: To control the generation of a re-reversal negative image, and the softening in the foot part of the titled material by incorporating a specified nucleus forming agent and a specified nucleus forming accelerating agent in a photosensitive material, and silver halide particles having at least two kinds of different mean particle sizes in an inner latent image type silver halide emulsion, respectively.

CONSTITUTION: The titled material comprises the nucleus forming agent shown by formula I and the nucleus forming accelerating agent shown by formulas II and/or III in the titled material, and the inner latent image type silver halide emulsion contains the silver halide particle having at least two kinds of the mean particle sizes. In the formulas, Z11 is a nonmetal atomic group necessary for forming a 5W6 membered heterocyclic ring, R11 and R12 are each an aliphatic group, etc., Q is an atomic group necessary for forming a 5 or 6 membered heterocyclic ring, Y is hydrogen, carbon or nitrogen atom, etc., R is thioether or amino group, etc., M is hydrogen atom, an alkali metal atom or an ammonium group, etc., Q1 is an atomic group necessary for forming a 5 or 6 membered heterocyclic ring capable of forming an iminosilver. Thus, the generation of the re-reversal negative image and the softening in the foot part of the titled material can be controlled.
