Abstract

Proposed is to calender materials used as coatings for xerographic members such as fuser members, pressure members, donor members and intermediate transfer members, wherein such members include rolls, belts, films, sheets, and the like. This technique is thought to improve the finish of overcoatings for such xerographic members.

Proposed is to calender materials used as coatings for xerographic members such as fuser members, pressure members, donor members and intermediate transfer members, wherein such members include rolls, belts, films, sheets, and the like. This technique is thought to improve the finish of overcoatings for such xerographic members.

Calendering is defined as a process used to press material between rollers or plates to smooth the material. In the case of xerographic belts, films, sheets and like web materials, the web material could be passed through two highly polished stainless steel rolls using a moderate nip pressure on the web to impart a polished surface finish to the coating web material. For xerographic roller members, the xerographic roller could be coated with the material overcoat, and subsequently, the xerographic roller brought in contact with a highly polished calender roll thereby impressing the surface finish of the calender roll on the coating of the xerographic roll, yielding a smooth glossy finish. This technique is proposed preferably for fluoroelastomer coatings such as volume grafted fluoroelastomer coatings.
