    (54) Imaging system with intermediate transfer member


    (57) Imaging apparatus for printing an image on a substrate (42) from a latent image formed on a latent image bearing surface (16) including:
       developing apparatus (22) for developing the latent image with a liquid developer to form a developed liquid toner image;
       a first intermediate transfer member (40);
       first transfer apparatus for transferring the developed image from the latent image bearing surface (16) to the first intermediate transfer member (40) at a first transfer region;
       eventually a second intermediate transfer member (47);
       second transfer means for transferring the developed image from the first image transfer member (40) to the second intermediate transfer member (7) or to the substrate (42) at a second transfer region; and
       third transfer apparatus for transferring the developed image from the second intermediate transfer member (47) to the substrate (42) when a second intermediate transfer is present.
       A first liquid toner image is transferred from the first surface (16) having a first temperature to the second surface (40) having a second liquid toner image thereon, by
       heating said second surface (40) to a second temperature at transfer, which second temperature is higher than said first temperature; and
       transferring said first and second images to the final substrate (42) or the second intermediate transfer member (47) from said second surface.
