| abstract | An image forming method for forming a black-and-white image with a gamma value of at least 8 is disclosed, which comprises processing an imagewise expsed negative type photographic material having at least one silver halide emulsion layer on a support, and containing a hydrazine derivative represented by formula (I) in the emulsion layer or in another hydrophilic colloid layer on the support, with a developer having a pH of 11.2 or less, wherein the silver halide grains are octahedral or tetradecahedral grains: <IMAGE> (I) wherein R1 represents an aliphatic or aromatic group, R2 represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an amino group, a carbamoyl group or an oxycarbonyl group, G1 represents a carbonyl group, a sulfonyl group, a sulfoxy group <IMAGE> group, or an iminomethylene group, and A1 and A2 each represents a hydrogen atom, or one is a hydrogen atom and the other is a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted arylsulfonyl group, or a substituted or unsubstituted acyl group. |
