Abstract
A thermal fusing assembly having an extended release life is described. Offset preventing fluid depleted from elastomeric offset preventing material on fuser members is replaced by offset preventing fluid from fluid supply means comprising specified elastomeric materials having an inherent capacity for offset preventing fluid, the fluid supply means being journaled in contact with the fuser members. The thermal fusing assembly comprises a heated fuser member which contacts toner images electrostatically adhered to a support surface to soften a heat-softenable toner to affect bonding thereof to the substrate, the fuser member having an elastomeric outer coating of offset preventing material; a backup or pressure roll forming a nip with the fuser member to advance the support surface so that the toner image on the support surface contacts the fuser member; and an offset preventing fluid supply roll or belt comprising the specified elastomeric material having an inherent supply of offset preventing fluid, the fluid supply roll or belt being journaled or extended in parallel relation with the fuser member.
