Abstract
An apparatus in which a fluid release material is applied to a fuser member. The fuser member is in communication with a backup member and a sheet of support material having particles thereon passing therebetween. A sealing arrangement prevents sidewise leakage of the release material along the longitudinal axis of the fuser member.
Claims6
An apparatus for applying a fluid release material to a fuser member in communication with a backup member as a sheet of support material having particles thereon passes therebetween with the particles contacting the fuser member, including:
- a housing defining a chamber for storing a supply of release material in operative communication with the fuser member;
- and
- a blade member disposed closely adjacent to the fuser member for controlling the thickness of the layer of release material applied to the fuser member, said blade member comprising truncated triangular pads extending in an outwardly direction, substantially normal to the edge of said blade member at opposed, spaced side marginal regions thereof, each truncated triangular pad being resiliently urged into engagement with the fuser member to prevent leakage of the release material thereat.
A fusing apparatus employed in an electrostatographic printing machine for affixing substantially permanently toner particles to a sheet of support material, including:
- a heated fuser roll;
- a backup roll in communication with said fuser roll such that the sheet of support material passes therebetween and the toner particles thereon contact said fuser roll;
- a housing defining a chamber for storing a supply of release material in operative communication with said fuser roll;
- and
- a blade member disposed closely adjacent to said fuser roll for controlling the thickness of the layer of release material applied to said fuser roll, said blade member comprising truncated triangular pads extending in an outwardly direction substantially normal to the edge of said blade member at opposed, spaced side marginal regions thereof, each truncated triangular pad being resilient urged into engagement with said fuser roll to prevent leakage of the release material thereat.
