Abstract

This invention related to an intermediate transfer member for electrophotography that includes a substrate; and a polymeric layer on said substrate wherein the polymeric layer comprises an organic titanate and a polymer selected from the group consisting of fluorosilicone, silicone, and a combination thereof.

Claims

1. An intermediate transfer member for the transfer of electrophotographic toner images comprising:

(a) a substrate; and

(b) a polymeric layer on said substrate, the polymeric layer having a surface that can carry an electrophotographic image on the surface of the polymeric layer and the surface on the polymeric layer can transfer that image to another surface wherein the polymeric layer comprises an organic titanate and a polymer selected from the group consisting of fluorosilicone polymers, silicone polymers, and a combination thereof.

2. An intermediate transfer member according to claim 1 wherein said intermediate transfer member is in the shape of an endless belt.

7. The intermediate transfer member of claim 1 having an electrophotographic image distributed over a surface of the polymeric layer.

8. The intermediate transfer member of claim 2 having an electrophotographic image distributed over a surface of the polymeric layer.

3. An intermediate transfer member for the transfer of electrophotographic toner images comprising:

(a) a substrate; and

(b) a polymeric layer on said substrate

wherein the polymeric layer comprises an organic titanate and a polymer selected from the group consisting of fluorosilicone polymers, silicone polymers, and a combination thereof and wherein said intermediate transfer member is in the shape of a drum.

5. An intermediate transfer member according to claim 3 wherein said organic titanate is selected from the group consisting of alkoxy titanates, ortho titanate esters, and a combination thereof.

9. The intermediate transfer member of claim 3 having an electrophotographic image distributed over a surface of the polymeric layer.

11. The intermediate transfer member of claim 5 having an electrophotographic image distributed over a surface of the polymeric layer.

4. An intermediate transfer member for the transfer of electrophotographic toner images comprising:

(a) a substrate; and

(b) a polymeric layer on said substrate

wherein the polymeric layer comprises an organic titanate and a polymer selected from the group consisting of fluorosilicone polymers, silicone polymers, and a combination thereof and wherein said intermediate transfer member is in the shape of a cylinder.

6. An intermediate transfer member according to claim 4 wherein said polymer comprises at least two functional groups selected from the group consisting of hydroxyl group, acetoxy group, and a combination thereof.

10. The intermediate transfer member of claim 4 having an electrophotographic image distributed over a surface of the polymeric layer.
