Abstract

Un rodillo revelador electrofotográfico se fabrica colando un prepolímero de uretano mezclado con un butadieno, un curador trifuncional y cloruro férrico en polvo. Después del curado, el rodillo se hornea, lo que oxida la superficie externa. La capa superficial oxidada es eléctricamente resistiva lo que es deseable en un rodillo revelador. Se obtiene un excelente rodillo revelador a un bajo costo de produccion.
