Abstract

Claims (27)

1. An endless fusing thick belt for an electrographic imaging device having a flexible tubular configuration of predetermined diameter, said endless fusing thick belt comprising;

an outside surface toner release layer comprised of a coating and a sleeve;

a silicone rubber layer positioned inside said outside surface toner release layer;

a steel layer positioned inside said silicone rubber layer; and

a silicone base layer positioned inside and affixed to the internal surface of said steel layer using an adhesive material.

2. The endless fusing thick belt of claim 1 wherein said outside surface layer is from about 20 to about 50 microns in thickness.

3. The endless fusing thick belt of claim 1 wherein said silicone rubber layer material is selected from the group consisting of black rubber or other suitable material having an IR energy absorption similar to black rubber.

4. The endless fusing thick belt of claim 3 wherein said silicone rubber layer material is from about 200 to about 500 microns in thickness.

5. The endless fusing thick belt of claim 1 wherein said steel layer is about 50 microns in thickness.

6. The endless fusing thick belt of claim 1 wherein said silicone base layer material is selected from the group consisting of translucent silicone foam, light color silicone foam, transparent silicone rubber, translucent silicone rubber, or other suitable low IR energy absorption material.

7. The endless fusing thick belt of claim 6 wherein said silicone base layer is from about 2 to about 40 shore A in hardness.

8. The endless fusing thick belt of claim 7 wherein said silicone base layer is from about 1 mm to about 2.5 mm in thickness.

9. An endless fusing thick belt for an electrographic imaging device having a flexible tubular configuration of predetermined diameter, said endless fusing thick belt comprising;

an outside surface toner release layer comprised of a coating and a sleeve;

a silicone rubber layer positioned inside said outside surface toner release layer;

a polyimide layer positioned inside said silicone rubber layer; and

a silicone base layer positioned inside and affixed to the internal surface of said polyimide layer using an adhesive material.

10. The endless fusing thick belt of claim 9 wherein said outside surface layer is from about 20 to about 50 microns in thickness.

11. The endless fusing thick belt of claim 9 wherein said silicone rubber layer material is selected from the group consisting of black rubber, or other suitable material having an IR energy absorption similar to black rubber.

12. The endless fusing thick belt of claim 11 wherein said silicone rubber layer material is from about 200 to about 500 microns in thickness.

13. The endless fusing thick belt of claim 9 wherein said polyimide layer is from about 50 to about 200 microns in thickness.

14. The endless fusing thick belt of claim 9 wherein said polyimide layer is made from unfilled polyimide.

15. The endless fusing thick belt of claim 9 wherein said polyimide layer is made from filled polyimide.

16. The endless fusing thick belt of claim 14 wherein said polyimide layer is from about 50 to about 200 microns in thickness.

17. The endless fusing thick belt of claim 9 wherein said silicone base layer material is selected from the group consisting of translucent silicone foam, light color silicone foam, transparent silicone rubber, translucent silicone rubber, or other suitable low IR energy absorption material.

18. The endless fusing thick belt of claim 9 wherein said silicone base layer is from about 2 to about 40 shore A in hardness.

19. The endless fusing thick belt of claim 18 wherein said silicone base layer is from about 1 mm to about 2.5 mm in thickness.
