Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
28 words
A heated fuser member comprising an elastomer layer and an anisotropic filler,
wherein said anisotropic filler is oriented in the elastomer layer so as to maximize
heat transfer.
Claim 2
Dependent Claim
45 words
A heated fuser member comprising a) a heating element, and b) an elastomer
layer comprising anisotropic fillers and optional fluorocarbon powder, wherein
said anisotropic filler is oriented in the elastomer layer so as to maximize heat
transfer from said heating element to said elastomer layer.
Claim 3
Dependent Claim
40 words
The heated fuser member in accordance with claim 1 or 2, wherein said anisotropic
filler has a major and a minor axis, wherein the major axis of the anisotropic filler is
substantially parallel to a radius of the fuser member.
Claim 4
Dependent Claim
30 words
The heated fuser member in accordance with any of claims 1 to 3, wherein a plane
substantially perpendicular to an elongated axis of said fuser member includes said
anisotropic fillers.
Claim 5
Dependent Claim
29 words
The heated fuser member in accordance with any of claims 1 to 4, wherein said
elastomer is selected from the group consisting of silicone elastomers,
fluoroelastomers and mixtures thereof.
Claim 6
Dependent Claim
47 words
The heated fuser member in accordance with claim 5, wherein said elastomer is a
fluoroelastomer selected from the group consisting of a) copolymers of
vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene, b) terpolymers of
vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene, and c)
tetrapolymers of vinylidenefluoride, hexafluoropropylene, tetrafluoroethylene and a
cure site monomer.
Claim 7
Dependent Claim
44 words
The heated fuser member in accordance with claim 5, wherein said
fluoroelastomer is a composite material selected from the group consisting of
volume grafted elastomers, titamers, grafted titamers, ceramers, grafted
ceramers, polyamide polyorganosiloxane copolymers, polyimide
polyorganosiloxane copolymers, polyester polyorganosiloxane copolymers, and
polysulfone polyorganosiloxane copolymers.
Claim 8
Dependent Claim
36 words
The heated fuser member in accordance with any of claims 1 to 7, wherein said
anisotropic filler is selected from the group consisting of graphite, aluminum oxide,
molybdenum disulfide, iron oxide, zinc oxide, and mixtures thereof.
Claim 9
Dependent Claim
35 words
The heated fuser member in accordance with any of claims 1 to 8, wherein said
elastomer layer further comprises an additional filler selected from the group
consisting of fluorocarbon powder, perfluoroether liquids, and mixtures thereof.
Claim 10
Dependent Claim
108 words
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 said electrostatic latent image to form a developed image on said charge
retentive surface; a transfer component to transfer the developed image from said charge
retentive surface to a copy substrate; and a heated fuser member to fuse said developed image to said copy substrate,
wherein said heated fuser member comprises an elastomer layer and an
anisotropic filler, wherein said anisotropic filler is oriented in the elastomer layer
so as to maximize heat transfer.
