Abstract
A method of forming images by silver salt diffusion transfer in which a photosensitive element which contains an imagewise exposed photosensitive silver halide emulsion layer is developed in the presence of a silver halide solvent using an alkaline processing composition, wherein at least part of the unexposed silver halide of the emulsion layer is formed into a transferable silver complex salt, at least part of the transferable silver complex salt is transferred to an image receiving layer to yield an image in the image receiving layer, wherein non-photosensitive silver precipitation nuclei are included in the photosensitive element. It is possible to obtain images without metallic luster in a stable manner.
