Abstract
An apparatus in which a metered quantity of release material is applied to a fuser roll. The release material is heated to maintain it substantially in a fluid state.
Claims4
An apparatus for metering a quantity of release material to a fuser member operatively associated with a back-up member to substantially fix particles to a sheet of support material passing therebetween, including:
- a housing defining a chamber for storing therein the release material, said housing comprising an inner shell defining the chamber for storing therein the release material, and an outer liner mounted contiguous with said inner shell and being made preferably from a thermally insulating material to substantially reduce loss of heat from the release material to the environment;
- a substantially tubular heating member positioned in contact with a portion of said inner shell for heating said housing to maintain the release material in a substantially fluid state;
- and
- means for applying release material from said housing to the surface of the fuser member.

A fusing apparatus employed in an electrostatographic printing machine for substantially permanently affixing toner particles to a sheet of support material, including:
- a heated fuser roll;
- a backup roll operatively associated with said fuser roll to enable the sheet of support material to pass therebetween with the toner particles contacting said fuser roll;
- a housing defining a chamber for storing therein the release material, said housing comprising an inner shell defining the chamber for storing therein the release material and an outer liner mounted contiguous with said inner shell and being made preferably from a thermally insulating material to substantially reduce loss of heat from the release material to the environment;
- a substantially tubular heating member positioned in contact with a portion of said inner shell for heating said housing to maintain the release material in a substantially fluid state;
- and
- means for applying release material from said housing to the surface of said fuser roll.
