PROBLEM TO BE SOLVED: To provide a heat developable photosensitive material having good adhesiveness and good electrostatic charge characteristics in heat development and in printing on a PS plate, less liable to generate black spots and having high maximum density (Dmax) and high contrast. SOLUTION: In the heat developable photosensitive material having an image recording layer containing the silver salt of an organic acid, silver halide, a binder and a reducing agent on one face of the base and a back coat layer comprising plural layers on the other face, a layer (back coat layer 1) of the back coat layer kept in contact with the base on which an undercoat layer is optionally disposed contains a fluorine-containing surfactant and the top layer (back coat layer 2) on the side with the disposed back coat layer contains a silicon-containing surfactant.
