Abstract:
1. A device for inking of a charge image with toner material in a printer or copier, comprising: a photoconductor band having a surface which comprises a photoconducting layer on which a charge image can be generated corresponding to a print image to be generated; an applicator roller having a surface on which a layer of toner particles has been applied at least on one region; a pivot arrangement for pivoting of the photoconductor band towards the applicator roller in a transfer printing region between the photoconductor band and the applicator roller in order to transfer at least one part of the toner particles present on the surface of the applicator roller onto the photoconductor band, and for pivoting the photoconductor band away from the applicator roller in the transfer printing region in order to prevent the transfer of the toner particles present on the surface of the applicator roller onto the photoconductor band; the pivot arrangement having a first roller over which the photoconductor band is directed before the transfer printing region; the pivot arrangement having a second roller over which the photoconductor band is directed after the transfer printing region; the applicator roller surface being curved outwards at a contact point with the photoconductor band, and the photoconductor band being pressed inwards by said outwardly-curved surface due to the pivoting towards the contact point and thereby partially encloses the outwardly-curved surface of the applicator roller; and the applicator roller being at least partially enclosed by the photoconductor band at the contact point as it is moved into the photoconductor band, whereby a depth of immersion lies in a range from 0.5 mm to 8 mm.
