    摘要: The present invention provides a heat-developable light-sensitive material having a support and a light-sensitive layer provided on the support. The heat-developable light-sensitive material contains dyes which are decolorized through reaction with a decolorizing agent during a development process. The dyes are non-diffusible and at least a part of decolorized dyes resulting from the development process is non-diffusible. Also provided is an image forming method using the heat-developable light-sensitive material. The present method provides images having excellent sharpness within a short period of time.
