Abstract

This invention relates to a novel conformable fuser device for use in an electro-statographic copying machine. In the embodiment of the novel conformable fuser device shown in the drawing, there is provided a pressure roll 10 which may be hard or soft and heated or not heated, a centrally heated soft and conformable fuser roll 12, the pressure roll and the fuser roil are mounted for rotation to permit the passage of paper therebetween, a centrally heated hard donor roll 14 for dispensing a release agent onto the fuser roll 12, a metering blade 16 for metering a predetermined amount of the release agent onto the donor roll, and a reservoir or sump 18 for holding the release agent. The donor roll 14 is in contact with the fuser roll and is frictionally driven thereby. The donor roll also may supply additional thermal energy required by the fuser roll to maintain the predetermined temperatures during copying cycles.
