Abstract
A liquid metering and coating device made of a liquid permeation control material including porous polytetrafluoroethylene, adhered to a porous support material of open-celled foam. The porous support and permeation control material contain mixtures of silicone oil and silicone rubber which bond to the porous support material and form an interconnected network of silicone rubber throughout the device. The device is suitable for use as a part of a toner fixation mechanism in a plain paper copying machine.
