Abstract
A fuser component useful in electrostatographic machines is provided. The fuser component has a substrate, and thereover a coating composition comprising a haloelastomer, such as, for example, a fluoroelastomer, and a filler having a particle size of less than about 3 micrometers and a particle hardness of greater than 3 on the Mohs' hardness scale.
Claims6
A fuser member, for fixing a developed image to a copy substrate, comprising:
- a substrate;
- an outer layer comprising a fluoroelastomer and a first filler, wherein said first filler has a particle size of 0.3 microns or less;
- wherein the first filler is selected from the group consisting of boron carbide, tungsten carbide, and combinations thereof;
- and
- wherein the fluoroelastomer is a tetrapolymer of vinylidenefluoride, hexafluoropropylene, tetrafluoroethylene, and a cure site monomer;
- and
- an intermediate layer located between the substrate and the outer layer, the intermediate layer comprising a fluoropolymer, an adhesive, and a second filler, the second filler having a particle size of 0.3 microns or less and being selected from the group consisting of boron carbide, tungsten carbide, and combinations thereof.

An image forming apparatus for forming images on a recording medium comprising:
- a charge-retentive surface to receive an electrostatic latent image thereon;
- a development component to apply toner to said charge-retentive surface to develop an electrostatic latent image to form a developed image on said charge-retentive surface;
- a transfer film component to transfer the developed image from said charge-retentive surface to a copy substrate;
- and
- a fusing component for fusing toner images to a surface of said copy substrate, said fusing component comprising:
- a substrate;
- an outer layer comprising a fluoroelastomer and filler particles,
- wherein said filler particles have a particle size of 0.3 microns or less and the filler particles are selected from the group consisting of boron carbide, tungsten carbide, and combinations thereof;
- and the fluoroelastomer is a tetrapolymer of vinylidenefluoride, hexafluoropropylene, tetrafluoroethylene, and a cure site monomer;
- and
- an intermediate layer located between the substrate and the outer layer, the intermediate layer comprising a fluoropolymer, an adhesive, and a second filler, the second filler having a particle size of 0.3 microns or less and being selected from the group consisting of boron carbide, tungsten carbide, and combinations thereof.
