Abstract: The invention is a method and apparatus for forming a relief structure by thermally developing a photosensitive element containing a composition layer capable of being partially liquefied. During thermal development, the photosensitive element is supported on a base member having an exterior surface that is textured. The textures for the exterior surface include a particular surface roughness and/or patterns.
