ABSTRACT:
An image forming method which comprises (A) exposing to an imagewise pattern of light a light-sensitive material having on a support at least (1) a light-sensitive silver halide, (2) a binder, and (3) a compound which is chemically involved in the reduction of the light-sensitive silver halide to silver under high temperature thereby causing the production or the release of a mobile dye, (B) heating the light-sensitive material in a substantially water-free condition to form the mobile dye with an imagewise distribution subsequently to or simultaneously with the exposure, and (C) transferring the mobile dye into a dye-fixing layer under high temperature and fixing it thereto wherein an acidic component participates chemically in the reaction system for forming the mobile dye after the conclusion of the mobile dye-forming reaction to bring about the desirable effect on lowering the fog density thereof.
