Abstract
A heat fixing device for use in an electrophotographic copying machine in which an electroconductive layer is provided in the surface of one of the fixing and pressure rolls for preventing charge built up upon the surface of the roll. The layer is preferably provided as an aluminum plated layer covered by a non-adhesive releasing layer made of a material such as tetrafluoroethylene or HTV or RTV silicone rubber. Provision of the electroconductive layer prevents an electric field from forming extending through a sheet carrying an image to be fixed thereby substantially entirely, eliminating any offset produced on the roll.
