Abstract
A fusing roller of the type having a thin internal resistance heating layer is electrically contacted by an internal conductive annular element positioned adjacent the end of the roller core. The resistance layer is applied to a common surface formed by the outside of the core and the annular element. Preferably, the resistance layer is covered by a protective layer. With this structure, the contacting device is protected from external damage, for example, from that caused by release oil contamination.
