Abstract: A photothermographic material having a Dmin and Dmax optical density. The material includes a support having hereon one or more thermally-developable imaging layers which are developable to produce an image when the photothermographic material is thermally processed; and an area disposed along a length of at least one edge of the photothermographic material, wherein the area has an optical density less than the Dmax and greater than the Dmin of the photothermographic material.

Abstract: A thermal processor for thermally developing an image in an imaging material. The processor includes an oven, at least one rotatable member positioned within oven, and a sleeve adapted to slideably fit over and selectively couple to at least a portion of the rotatable member. The sleeve has an exterior surface coated with a layer of polymer material and is positioned such that the layer of polymer material contacts and transports the imaging material through the oven as the at least one rotatable member rotates.
