Abstract
A seamless conductive toner supply brush may comprise conductive fibers flocked onto a metal shaft or rigid conductive core. The shaft/core may be coated with a conductive adhesive and then flocked with fibers about 2-5 mm in length. The brush may be useful as a toner supply brush for supplying toner to a developer member in electrophotographic devices.
Claims23
A toner supply brush comprising:
- a conductive core;
- an adhesive layer overlying the outer surface of the core;
- and
- a plurality of fibers attached to the core by the adhesive layer wherein the fibers exhibit an electrical resistance of less than 106 ohms/cm.
1 more element
