Abstract
A fuser member including a substrate, and thereover, an outer layer comprising a crosslinked fluorinated polyimide and a curing agent is described. The fluorinated polyimide comprises: wherein Ar1 and Ar2 independently represent an aromatic group of from about 6 carbon atoms to about 60 carbon atoms; and at least one of Ar1 and Ar2 further contains a fluoro-pendant group; and wherein the fluorinated polyimide includes an active site capable of reacting with the curing agent.
Claims20
A fuser member comprising a substrate, and thereover, an outer layer comprising a crosslinked fluorinated polyimide with a curing agent, wherein said fluorinated polyimide comprises:
- wherein Ar1 and Ar2 independently represent an aromatic group of from about 6 carbon atoms to about 60 carbon atoms;
- and at least one of Ar1 and Ar2 further contains a fluoro-pendant group;
- and
- wherein the fluorinated polyimide includes an active site capable of reacting with the curing agent.
The fuser member of claim 12, wherein the active site comprises from about 0.5 to about 50 weight percent of the fluorinated polyimide.
A fuser member comprising a substrate, and thereover, an outer layer comprising a crosslinked product resulted from a coating composition comprising a fluorinated polyimide and a curing agent, wherein said polyimide comprises:
- wherein Ar1 and Ar2 independently represent an aromatic group of from about 6 carbon atoms to about 60 carbon atoms;
- and at least one of Ar1 and Ar2 further contains a fluoro-pendant group;
- and
- wherein the fluorinated polyimide includes an active site capable of reacting with the curing agent.
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 the charge-retentive surface to develop an electrostatic latent image to form a developed image on the charge retentive surface;
- a transfer component to transfer the developed image from the charge retentive surface to a copy substrate;
- and an oil-less fuser member for fusing toner images to a surface of the copy substrate, wherein said oil-less fuser member does not require the presence of a fuser oil for release, said oil-less fuser member comprising a substrate, and thereover, an outer layer comprising a fluorinated polyimide and a curing agent, wherein said fluorinated polyimide comprises:
- wherein Ar1 and Ar2 independently represent an aromatic group of from about 6 carbon atoms to about 60 carbon atoms;
- and at least one of Ar1 and Ar2 further contains a fluoro-pendant group;
- and
- wherein the fluorinated polyimide includes an active site capable of reacting with the curing agent.
