ABSTRACT:
A device for transferring an image present on a belt (1) driven at a first speed to an intermediate support (14) driven at a second speed. A pressing element (28) keeps the belt (1) and the intermediate support (14) in contact with one another during the image transfer, the belt (1) assuming the speed of the intermediate support (14) in the contact zone under the influence of frictional forces. A belt storage device (27,33) disposed between the belt drive means (7,8) and the contact zone stores the length difference arising from the difference in the belt speed at the belt drive means and at the contact zone. The belt length present in the belt storage device (27,33) is measured. The speed of the intermediate support (14) is controlled in dependence on the length measured.
