Image formation method

Abstract

An image formation method, which comprises the steps of imagewise exposing a silver halide photographic material comprising a support having thereon at least one layer of a silver halide emulsion chemically sensitized with at least one selenium or tellurium compound, and then subjecting the material to development-processing with a developer containing substantially no dihydroxybenzene developing agent but containing a developing agent represented by the following formula (I): ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and each represents a hydroxyl 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 are the same or different and each represents a hydroxyl group, a carboxyl group, an alkoxy group, a hydroxyalkyl group, a carboxyalkyl group, a sulfo group, a sulfoalkyl group, an amino group, an aminoalkyl group, an alkyl group, an aryl group or a mercapto group, or P and Q may represent an atomic group capable of forming a 5- to 8-membered ring by combined with each other and further by associating with two vinyl carbon atoms to which R.sub.1 and R.sub.2 are attached respectively and one carbon atom to which Y is attached; and Y represents .dbd.O or .dbd.N--R.sub.3, wherein R.sub.3 represents a hydrogen atom, a hydroxyl group, an alkyl group, an acyl group, a hydroxyalkyl group, a sulfoalkyl group or a carboxyalkyl group.
