Abstract
In a transfer unit, a rotating transfer element is arranged adjacent a charge image carrier that takes toner images from the charge image carrier and supplies the images to a transfer printing station. A scoop element applies carrier fluid to the transfer element. A friction element is provided after the scoop element adjacent to the transfer element at such a distance from the transfer element that a gap between the transfer element and the friction element is substantially completely filled with the carrier fluid, the friction element and the transfer element rotating with different speeds. Residual toner remaining on the transfer element after the transfer printing is loosened by friction forces.
