ABSTRACT:
High efficiency transfer of liquid toner image from an photoconductor onto an image receiver (e.g., plain paper, transparency film, and the like) using a simple and direct, one-step process, is provided. The transfer is effected using a hard (non-conformable) substrate, at least one conformable intermediate mat, the photoconductor having a release surface comprising a siloxane, the image receiver, a roller, and a source of heat and pressure. One conformable layer may be employed, resulting in two possibilities. In the first possibility, the roller comprises the source of heat and pressure and the conformable layer supports the photoconductor layer. A non-conformable layer supports the conformable layer. In the second possibility, the source of heat and pressure is on that surface of the photoconductor opposite that on which the toner image is carried and the conformable layer is positioned between the roller and the image receiver. In yet another embodiment, two conformable layers are employed, with a first conformable layer supporting the photoconductor layer and a second conformable layer positioned between the roller and the image receiver, with a non-conformable layer supporting the first conformable layer. The roller provides the source of heat and pressure.
