Imaging elements, such as photographic, electrostatographic and thermal imaging elements, comprised of a support, an image-forming layer and an electrically-conductive layer consisting essentially of electrically-conductive fine particles, such as antimony-doped tin oxide particles and, as a binder, water-insoluble polymer particles containing sulfonic acid groups. The use of water-insoluble polymer particles containing sulfonic acid groups as a binder in the electrically-conductive layer provides a layer with a high degree of conductivity at low concentrations of electrically-conductive fine particles.
