An apparatus, system, and method for processing photothermographic elements. The apparatus thermally develops a photothermographic element by heating the photothermographic element between a heated member, having a resilient layer, and a plurality of rollers. The apparatus can be a component of other apparatus and systems including those having the ability to expose the photothermographic element to form a latent image.
