Device for adjustment of the electrical potential in the case of a moving tapelike backing of half conductor material for ink particles in the case of an electrographic pressure - or copier

摘要

Adjacent to the carrier (1), for example a belt, is a into a metal profile (2) embedded discharging unit (3) is positioned by means of which the carrier (1) is guided. The metal section (2) is connected to an electrical potential, for example ground potential. The discharging unit (3) has a relative to the metal profile (2) has an electrically insulated discharging chamber (4), in which by means of an ionizer (6) ions generated on the carrier (1), can be deflected by means of which the carrier (1) to the electrical potential of the metal profile section (7) is transferred. Advantage is the non-contact charge reversal of the carrier (1).
