Abstract

An electrostatic charging apparatus is shown above in which charging current reaching an imaging surface from a corona discharge device is automatically regulated. The corona device comprises a wire electrode 55 partially surrounded by a grounded metal shield 56. The wire 55 is energized by an a.c. corona generating source 62 which in turn is biased to a d.c. potential provided by a source 63. An imaging surface 58 in the form of a drum comprising a photoconductive surface carried by a con- ductive substrate is rotated adjacent the corona charging device 40,
