Abstract

---

This invention relates to a method and apparatus for thermally developing a photosensitive element. The thermal development method includes heating the photosensitive element to a temperature sufficient to cause a portion of a composition layer in the element to liquefy, soften, or melt, contacting the heated photosensitive element with a development medium to absorb the liquefied portion at a contact location, and removing the development medium from the photosensitive element with a remover at a location away from the contact location.
