Abstract
An image formation method comprising imagewise exposing a silver halide light-sensitive material comprising a support having thereon a light-sensitive silver halide, a binder, a slightly water soluble basic metal compound, and a dye composition which is decolorized or discolored on heat development; contacting the surface of the light-sensitive material with a sheet coated with a binder and a compound which forms a complex with a metal ion constituting the basic metal compound and heating them in the presence of a reducing agent and water after or during the imagewise exposing; and peeling off the sheet to obtain an image on at least the light-sensitive material and the sheet, wherein the dye composition comprises an oil-soluble dye formed by a leuco dye and a color developer.
