ABSTRACT:
A process for forming an image by silver salt diffusion transfer comprising developing a light-sensitive element which comprises a support having provided thereon a light-sensitive silver halide emulsion layer which has been imagewise exposed to light by an alkaline processing composition in the presence of a silver halide solvent so that at least a part of silver halide unexposed in said emulsion layer is converted to a transferable silver complex salt, and then transferring at least a part of said silver complex salt to an image-receiving layer containing a silver precipitating agent to form an image on said image-receiving layer, wherein the concentration of said silver precipitating agent in said image-receiving layer is in the range of from 2.times.10.sup.-6 to 8.times.10.sup.-6 mol/m.sup.2 and at least one of said light-sensitive element and said alkaline processing composition contains at least one of a compound represented by formula (I) and a compound represented by formula (II) ##STR1## wherein R.sub.1 represents a phenyl group or a phenyl group substituted by an alkyl group having 1 or 2 carbon atoms; R.sub.2 and R.sub.3 each represents a hydrogen atom, an alkyl group having from 1 to 3 carbon atoms, or a hydroxyalkyl group having from 1 to 3 carbon atoms; and R.sub.4 and R.sub.5 each represents a hydrogen atom, an alkyl group having from 1 to 3 carbon atoms, a phenyl group, a phenyl group substituted by an alkyl group having from 1 to 3 carbon atoms; ##STR2## wherein R.sub.6 and R.sub.7 each represents a hydrogen atom or an alkyl group having from 1 to 3 carbon atoms; R.sub.8 represents an alkyl group having from 1 to 4 carbon atoms; and n represents an integer of from 1 to 3.
