Abstract
An image forming apparatus using dry silver salt material includes a photosensitive member having a base material and reducing material, photosensitive silver halide and organic silver salt which are on the base material; optical system for projecting information light onto the photosensitive member; auxiliary exposure optical system for uniformly exposing an entire surface of the photosensitive member; and a heating for uniformly heating the photosensitive member.
