ABSTRACT:
A charge roller made from a mixture of urethane, polybutadiene, a polyether diol, ferric chloride, and antimony doped tin oxide with or without carbon black. The roller has a very high outer surface electrical resistance from baking the roller to oxidize the polybutadiene. The charge roller is achieved at low production cost and functions well even with charging by a DC potential with an AC overlay.
