Abstract
The present teachings described a bias charging member and a method of manufacture. The bias charging member includes a conductive core and an outer surface layer disposed on the conductive core. The outer surface layer includes a water soluble polyamide resin, and a water soluble aminoplast resin.
Claims19
A bias charging member comprising:
- a) a conductive core, and
- b) an outer surface layer disposed on the conductive core, the outer surface layer comprising:
- a water soluble polyamide resin, a wetting agent comprising a water soluble silicone copolymer and a water soluble aminoplast resin.
A method of manufacturing a bias charging member comprising:
- mixing a water soluble polyamide resin, a water soluble aminoplast resin, an acid catalyst, a water soluble silicone copolymer wetting agent, water, carbon black and polyamide particles to obtain a dispersion;
- coating the dispersion on a bias charging roll substrate;
- and
- heating the coating to form an outermost layer.
