ABSTRACT:
A fusing roller of the type having a thin resistance heating layer near its surface has a core made of a thermally and electrically insulative material, such as glass, which has a coefficient of thermal expansion comparable to that of the resistance heating layer. The roller can then withstand a high temperature curing process for other layers without separation of the resistance layer from the core.
