Wound magnetic roll developer tube and method of manufacture

摘要

The developer roll includes a wound roll of media (102). The wound roll is formed from a sheet of the media (100). A resin (104) is at least partially absorbed by the edge of the wound roll. The layer of resin and the roll of media are selected of materials to obtain a decay rate relating to the electrical response of the roll to the applied voltage differential. The wound roll is located on an edge of a metal core (106). The layer has a conductivity of 105 to 107 ohms. The layer comprises a conductive material. The conductive material comprises a thermoset resin. The sheet of media has a thickness of 0.001 to 0.008 inches. The sheet of media is wrapped at least 360 degrees. The media comprises woven cloth or carbon.
