ELEKTROGRAFISKT REGISTRERINGSFORFARANDE SAMT APPARAT FOR GENOMFORANDE AV DETSAMMA

摘要

An electrographic process and device are provided wherein a dielectric recording member is arranged between two electrodes to one of which is adherably bound electronically conductive toner powder, the toner powder providing an electronically conductive path between the electrode to which it is bound and the adjacent surface of the dielectric member, and a voltage applied to the electrodes for a time and of a magnitude sufficient to generate a force pattern of intelligence on the toner which enables toner deposition on the recording member in accordance with the force pattern. The force pattern is generated directly on the toner rather than on the recording member which is passive in the operation of this invention.
