Color-developing agent, silver halide photographic light-sensitive material and image-forming method

A silver halide photographic light-sensitive material, comprising a compound represented by formula (I) that is contained in at least one hydrophilic colloid layer provided on a base:

• ##STR30## wherein Z.sup.1 represents a carbamoyl group, Q.sup.1 represents a group of nonmetal atoms required to form a 5- or 6-membered aromatic ring together with the C, Q.sup.2 represents an aromatic heterocyclic residue, Y.sup.1 represents a group capable of substitution onto the aromatic ring, m is 1 or 2, and n is an integer of 0 to 3.

The silver halide photographic light-sensitive material as claimed in claim 14, wherein the formula (I) is represented by formula (III):

• ##STR31## wherein R.sup.6 and R.sup.7 each represent a hydrogen atom or a substituent, and Q.sup.1, Q.sup.2, Y.sup.1, m, and n each have the same meanings as defined in formula (I).

An image-forming method, comprising the steps of

• subjecting a silver halide photographic light-sensitive material to exposure to light image-wise, and
• developing the silver halide photographic light-sensitive material in the presence of a color-developing agent represented by the formula (I):
• ##STR32## wherein Z.sup.1 represents a carbamoyl group, Q.sup.1 represents a group of nonmetal atoms required to form a 5- or 6-membered aromatic ring together with the C, Q.sup.2 represents a heterocyclic residue, Y.sup.1 represents a group capable of substitution onto the aromatic ring, m is 1 or 2, and n is an integer of 0 to 3.
