Abstract

An image transfer blanket usable with an image forming apparatus includes a main blanket body, a plurality of release layers configured to receive and transfer an image, each release layer disposed across from opposites sides of the main blanket body, and a plurality of soft layers configured to conform to a substrate onto which the image is transferred, each soft layer disposed between a respective release layer and the main blanket body.

Claims

1. An image transfer blanket usable with an image forming apparatus, the image transfer blanket comprising:

a main blanket body;

a plurality of release layers configured to receive and transfer an image, each release layer disposed across from opposites sides of the main blanket body; and

a plurality of soft layers configured to conform to a substrate onto which the image is transferred, each soft layer disposed between a respective release layer and the main blanket body.

2. The image transfer blanket according to claim 1, wherein the plurality of release layers comprises a first release layer and a second release layer.

3. The image transfer blanket according to claim 2, wherein the plurality of soft layers comprises a first soft layer and a second soft layer.

4. The image transfer blanket according to claim 3, wherein the first release layer is disposed on the first soft layer, the first soft layer is disposed on the main blanket body, the main blanket body is disposed on the second soft layer, and the second soft layer is disposed on the second release layer.

5. The image transfer blanket according to claim 1, wherein the main blanket body comprises one of acrylic rubber, netryl rubber and polyurethane.

6. The image transfer blanket according to claim 1, wherein the main blanket body comprises a plurality of conductive layers configured to create an electrostatic field to assist image transfer and at least one compressible layer configured to conform to the substrate onto which the image is transferred.

7. The image transfer blanket according to claim 6, wherein the plurality of conductive layers comprises a first conductive layer and a second conductive layer, and the compressible layer is disposed between the first conductive layer and the second conductive layer.

8. The image transfer blanket according to claim 1, wherein the main blanket body comprises:

a plurality of conductive layers configured to create an electrostatic field to assist image transfer;

a plurality of compressible layers configured to conform to the substrate onto which the image is transferred; and

a fabric layer configured to provide mechanical strength to support the plurality of compressible layers.

9. The image transfer blanket according to claim 8, wherein the plurality of conductive layers comprises a first conductive layer and a second conductive layer, and the plurality of compressible layers include a first compressible layer and a second compressible layer.

10. The image transfer blanket according to claim 9, wherein the first conductive layer is disposed on the first compressible layer, the first compressible layer is disposed on the fabric layer, the fabric layer is disposed on the second compressible layer, and the second compressible layer is disposed on the second conductive layer.

11. The image transfer blanket according to claim 3, wherein a thickness of the first soft layer and the second soft layer are approximately equal.

12. The image transfer blanket according to claim 3, wherein a thickness of the first soft layer and the second soft layer are not equal.

13. The image transfer blanket according to claim 2, further comprising:

a normal state in which the first release layer is proximate to a photo imaging member (PIP) of the image forming apparatus and configured to receive an image therefrom and the second release layer is proximate to an intermediate drum of the image forming apparatus; and

a reverse state in which the second release layer is proximate to the PIP and configured to receive the image therefrom and the first release layer is proximate to the intermediate drum.

14. The image transfer member according to claim 2, wherein each of the first and second release layer has a thickness of approximately five microns.

15. An image forming apparatus including an image transfer blanket having a normal state and a reverse state, the apparatus comprising:

a photo imaging member (PIP);

an intermediate drum; and

an image transfer blanket disposed on the intermediate drum, the image transfer blanket comprising;

a main blanket body;

a first and a second release layer configured to receive an image from the PIP and transfer the image to a substrate, each release layer disposed across from opposites sides of the main blanket body; and

a plurality of soft layers configured to conform to the substrate onto which the image is transferred, each soft layer disposed between a respective release layer and the main blanket body;

wherein, in the normal state, the first release layer is proximate to the PIP to receive the image therefrom and the second release layer is proximate to the intermediate drum and, in the reverse state, the second release layer is proximate to the PIP to receive the image therefrom and the first release layer is proximate to the intermediate drum.
