Abstract
An apparatus for transferring toner from an incompressible, flexible magnetic image-storage medium to paper. The apparatus includes a cylindrical drum having a layer of resilient backing material on an inner support structure. An image-storage medium is slidably disposed on the backing material. A pressure roller also having a resilient surface layer is placable against the roller to form, in combination therewith, a pinch roller through which paper is transported during toner transfer. Deformation of the respective resilient layers in the roller and drum during transfer produces a complimentary slip action between the resilient backing and image-storage medium. This allows the paper and medium to move together without smearing the associated toner images.
