Abstract
Provided is a heating fixing roller which includes a tubular base member and a fluororesin layer provided on an outer circumferential surface of the base member directly or through an adhesive layer, the heating fixing roller being characterized in that the fluororesin layer contains phosphorus-doped tin oxide. The heating fixing roller has a surface resistance capable of stably and effectively preventing the occurrence of electrostatic offsets, and also has an excellent releasing property. Also provided is a process for producing the heating fixing roller, characterized by including the steps of applying a fluororesin dispersion containing an aqueous dispersion of phosphorus-doped tin oxide onto a tubular base member or an adhesive layer disposed on an outer circumferential surface of the tubular base member, and then sintering the fluororesin.
