Abstract:
A method of developing a heat-developable image-recording material, comprising a support, at least one image-forming layer on the support, and at least one protecting layer on the image-forming layer, comprising the step of:placing said image-recording material in a heat development apparatus, comprising: a roller coming into a driving contact with a surface of said material on the side having the image-forming layer, and a smooth surface coming into a sliding contact for transport with a surface of said material opposite to said surface on the side having said image-forming layer, wherein at the temperature where said development is carried out, the ratio is 3.1 to 28.0 of the coefficient of friction, &mgr;e, between said surface on the side having said image-forming layer and a surface of said roller of said heat development apparatus, to the coefficient of friction, &mgr;b, between said surface of said material opposite to said surface on the side having said image-forming layer and said smooth surface of said heat development apparatus, wherein the coefficient of friction, &mgr;b, is within the range of 0.1 to 0.9; wherein said at least one image forming layer comprises an organic silver salt, a reducing agent and a photosensitive halide.
