Abstract
Provided is a roller for an image-forming apparatus which includes a base member and a fluororesin layer provided on an outer circumferential surface of the base member directly or through an adhesive layer, the roller for an image-forming apparatus being characterized in that the fluororesin layer contains phosphorus-doped tin oxide. The roller for an image-forming apparatus 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 roller for an image-forming apparatus, characterized by including the steps of applying a fluororesin dispersion containing an aqueous dispersion of phosphorus-doped tin oxide onto a base member or an adhesive layer disposed on an outer circumferential surface of the base member, and then sintering the fluororesin.
