Abstract
Rolls include a core and a glass outer coating on the core. The glass can be electrically charged and discharged. The outer coatings have smooth finishes and controlled electrical properties. The outer coatings can also provide selected mechanical, chemical and thermal properties. The rolls can be used in various applications in which controlled electrical properties are desired. For example, the rolls can be used as charge donor rolls in electrostatographic imaging apparatus.
