Title:
CONDUCTIVE RUBBER COMPOSITION AND CONDUCTIVE RUBBER ROLLER USING THE SAME
Document Type and Number:
Japanese Patent JP2006258967
Kind Code:
A
Abstract:
To provide a conductive rubber composition having low hardness and contamination resistance, and to provide a conductive rubber roller using the composition.
At least an elastic layer is formed on a conductive core metal. The elastic layer is formed by using a conductive rubber composition prepared by adding at least one kind of rosin resin, coumarone resin and terpene resin having 90°C to 180°C softening point to a conductive rubber. The volume resistivity of the conductive rubber composition ranges from 103 Ω cm to 109 Ω cm. Then a surface layer is formed on the elastic layer to manufacture a conductive rubber roller.
