Abstract
An image-forming method comprising heating a light-sensitive material in a substantially water-free condition is described. The method uses a light-sensitive material comprised of a support having thereon at least light-sensitive silver halide, a binder, an electron donor and/or electron-transfer agent capable of reducing light-sensitive silver halide, and an immobile dye-releasing substance releasing a mobile dye upon reduction with the electron donor and/or electron-transfer agent.
