Image-forming process

An image-forming process for a silver halide photographic material having at least one silver halide emulsion layer on a support and containing a hydrazine compound in the emulsion layer or in another layer which comprise development processing in a developing solution after exposing, wherein the above hydrazine compound is represented by the following formula (I) and the developing solution contains a developing agent represented by the following formula (II) and substantially no dihydroxybenzene developing agent:

• ##STR15## wherein R.sub.1 represents an aliphatic group or an aromatic group;
• R.sub.2 represents a hydrogen atom, an alkyl group, an aryl group, an unsaturated heterocyclic group, an alkoxy group, an aryloxy group, an amino group, a hydrazino group, a carbamoyl group, or an oxycarbonyl group;
• G.sub.1 represents --CO--, --SO.sub.2 -, --SO--, ##STR16## --CO--CO--, a thiocarbonyl group, or an iminomethylene group;
• both A.sub.1 and A.sub.2 represent a hydrogen atom, or one represents a hydrogen atom and the other represents an alkylsulfonyl group, an arylsulfonyl group, or an acyl group;
• R.sub.3 is the same as those groups defined for R.sub.2 or may be different from R.sub.2 ;
• provided that at least one of R.sub.1 and R.sub.2 has a ballast group, at least one of R.sub.1 and R.sub.2 has a group enhancing adsorption to a silver halide grain surface, R.sub.1 has a trialkylammonium group, or R.sub.1 has an alkylthio group including a cycloalkylthio group or an arylthio group, except that R.sub.1 is not ##STR17## wherein R.sub.7 represents a group containing three or more units of --CH.sub.2 CH.sub.2 O-- in sequence or a group containing a pyridinum group;
• and n is 1 or 2;
• ##STR18## wherein R.sub.21 and R.sub.22 each represent a hydroxy group, an amino group, an acylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, an alkoxycarbonylamino group, a mercapto group, or an alkylthio group;
• P and Q each represent a hydroxy group, a carboxyl group, an alkoxy group, a hydroxalkyl group, a carboxylalkyl group, a sulfo group, a sulfoalkyl group, an amino group, an aminoalkyl group, an alkyl group, or an aryl group, or P and Q represent an atomic group forming a 5- or 7-membered ring together with two vinyl carbon atoms on which R.sub.21 and R.sub.22 are substituted and a carbon atom on which Y is substituted;
• Y represents .dbd.O or .dbd.N--R.sub.23 ;
• and R.sub.23 represents a hydrogen atom, a hydroxyl group, an alkyl group, an acyl group, a hydroxyalkyl group, a sulfoalkyl group, or a carboxyalkyl group.
