Abstract

A hot roll, for use in a xerographic hot roll fuser, is made by coating a hollow aluminum cylinder with an elastomer, as by the use of an injection molding machine. After molding, the external surface of the elastomer cylinder is ground slightly to improve its concentricity. Thereafter, this ground external surface is subjected to the chemical influence of an acid. After a predetermined time period, the acid treatment is terminated and the roll is washed in water. The resulting hot roll, whose external surface has been chemically modified, possesses improved dry-release properties.
