Abstract

A capacitive energy-storing unit is discharged through a flash discharge lamp, to cause the latter to edit radiation to fix fusable toner on copying material in an electrophotographic copying machine. The charging circuit for the capacitive energy-storing unit is connectable to a source of periodic voltage, and it includes a charging impedance and an electronic charging switch. The charging switch is periodically rendered conductive, but the firing angle of the charging switch is automatically varied relative to the periodic voltage in dependence upon the voltage developed across the capacitive energy-storing unit.
