摘要： An image forming method using a heat developable light-sensitive material is disclosed. The light-sensitive material is lowered in curling caused by humidity changing at room temperature or heating at development. The method comprises the following steps ofimagewise exposing to light a heat developable light-sensitive material comprising a paper support having thereon a subbing layer comprising a hydrophobic resin and a light-sensitive layer being provided on the subbing layer, in which the light-sensitive layer comprises a hydrophilic binder, light-sensitive silver halide grains and a dye providing substance,developing the light-sensitive material be heating,contacting the light-sensitive material with a dye-receiving material, andtransferring a diffusible dye formed in the light-sensitive material to the dye-receiving material in the presence of a solvent. The hydrophobic resin of the subbing layer has a glass transition point of from 30.degree. C. to 250.degree. C.The above object of the invention is accomplished by an image forming method comprising the following steps ofimagewise exposing to light a heat developable light-sensitive material comprising a paper support having thereon a subbing layer comprising a hydrophobic resin having a glass transition point of from 30.degree. C. to 250.degree. C. and a light-sensitive layer being provided on the subbing layer, in which the light-sensitive layer comprises a hydrophilic binder, light-sensitive silver halide grains and a dye providing substance,developing the light-sensitive material by heating, contacting the light-sensitive material with a dye-receiving material, andtransferring a diffusible dye formed in the light-sensitive material in the developing step to the dye-receiving material in the presence of a solvent capable of dissolving the diffusible dye.
