Thermally processable imaging elements in which the image is formed by imagewise heating or by imagewise exposure to light followed by uniform heating are comprised of a support, a thermographic or photothermographic imaging layer, a protective overcoat layer which is an outermost layer on the same side of the support as the imaging layer, a backing layer which is an outermost layer on the side of the support opposite to the imaging layer, and an electroconductive agent in at least one layer of the element. Each of the protective overcoat layer and the backing layer contains a fluorosurfactant in an amount sufficient to serve as a triboelectric charge control agent and effective in providing essentially the same triboelectric charging characteristics to the backing layer as to the protective overcoat layer.
