Abstract
In an electrophotographic copier a fusing station is provided at which a toner image previously formed on a copy carrier is fixed on the carrier by fusing. The fusing station includes a flash tube which, when discharged, produces the heat required for the fusing operation. The electrical energy required by the flash tube is supplied from a flash capacitor. To avoid current spikes during charging of the flash capacitor the same receives its current from a drive system which includes a motor-driven generator in circuit with the flash tube; the inertia of the drive system acts as a buffer between the flash capacitor and the current supply source and prevents the occurrence of current peaks during the charging of the capacitor.
