To provide a method for producing a heat developable recording material by which a good photosensitive layer free of the mark of a hole and scratch and less liable to generate dust due to scratch can be formed.

The method for producing a heat developable recording material includes a step for conveying a support with an undercoat layer containing a polymer having ≤100°C glass transition temperature Tg while sucking and holding the undercoat layer side of the support by a suction drum wrapped with woven cloth and a step for forming a photosensitive layer containing silver behenate on the undercoat layer.
