    (54) Image transfer apparatus and method


    (57) An imaging system including an image bearing surface (16) and an intermediate transfer member (40) operative for transfer of liquid toner images from the image bearing surface (16) to a substrate (42) provides for first transfer engagement between the intermediate transfer member (40) and the image bearing surface (16) for transfer of an image from the image bearing surface to the intermediate transfer member (40) at a first pressure, producing deformation of the intermediate transfer member (40) to a first deformation degree. The system also provides for second transfer engagement between the intermediate transfer member (40) and the substrate (42) for transfer of the image from the intermediate transfer member to the substrate at a second pressure, producing deformation of the intermediate transfer member (40) to a second deformation degree. In one preferred embodiment the intermediate transfer member (40) includes a compressible layer having a transfer surface, a backing layer disposed away from the image bearing surface and a heating layer. The heating layer is disposed intermediate the backing layer and the transfer surface.
