Abstract
A heat development processor includes a heat roller whose peripheral surface is heated to a predetermined temperature, the heat roller being adapted to transport in close contact therewith a heat-developable light-sensitive material with a latent image formed thereon, so as to heat develop the heat-developable light-sensitive material; and a backup roller disposed in face-to-face relation with the heat roller and having a gap between the same and the heat roller, the gap corresponding to or greater than the thickness of the heat-developable light-sensitive material. Since a gap is provided between the heat roller and the backup roller, a nipping force does not act between them, making it possible to squeeze out steam from between the heat-developable light-sensitive material and the peripheral surface of the heat roller.
