Abstract
An imaging system including an image bearing surface and an intermediate transfer member having an image transfer surface and being operative for transfer of toner images from the image bearing surface to the image transfer surface and for subsequent transfer to a substrate. The intermediate transfer member includes a backing layer, a compressible layer disposed between the image transfer surface and the backing layer and a heating layer which is disposed between the backing layer and the compressible layer.
Claims22
An imaging system comprising:
- an image bearing surface, and
- an intermediate transfer member having an image transfer surface and being operative for transfer of toner images from said image bearing surface to said image transfer surface and for subsequent transfer to a substrate, said intermediate transfer member also comprising:
- a backing layer;
- a compressible layer disposed intermediate said image transfer surface and said backing layer;
- and
- a heating layer disposed intermediate said backing layer and said compressible layer.
An imaging system comprising:
- an image bearing surface;
- and
- an intermediate transfer member having an image transfer surface and being operative for transfer of toner images from said image bearing surface to said image transfer surface and for subsequent transfer to a substrate, said intermediate transfer member also comprising:
- a backing layer;
- a conductive layer disposed intermediate said backing layer and said image transfer surface and operative to apply an electric field to said image to enhance transfer of toner images from said image bearing surface to said intermediate transfer member;
- and
- a heating layer disposed intermediate said backing layer and said transfer surface.
An intermediate transfer blanket for transfer of liquid toner images from a first surface to a second surface and comprising:
- a transfer surface for operative engagement with said first surface and said second surface;
- a resilient layer;
- a sponge layer which is relatively softer than the resilient layer;
- and
- an area heater disposed between said sponge layer and said resilient layer.
An imaging system comprising:
- a drum having an image bearing surface;
- and
- an intermediate transfer member operative for transfer of toner images from said image bearing surface to a transfer surface of said intermediate transfer member and for subsequent transfer to a substrate, said intermediate transfer member comprising:
- a blanket heater layer comprising a plurality of thin elongate members;
- means for applying a first voltage to said blanket heater to heat said blanket;
- and
- means for applying a second voltage between said blanket heater and said drum to improve transfer of said toner images from said image bearing surface to said intermediate transfer member.
An imaging system comprising:
- an image bearing surface;
- and
- an intermediate transfer member having an image transfer surface and being operative for transfer of toner images from said image bearing surface to said image transfer surface and for subsequent transfer to a substrate, said intermediate transfer member also comprising:
- a backing layer;
- a compressible layer having a thickness less than 1 cm and disposed intermediate said image transfer surface and said backing layer;
- and
- a heating layer disposed intermediate said backing layer and said transfer surface.
