ABSTRACT:
A charging device comprises a contact piled cloth which is formed of pliable material, has an electric resistance chosen to be 10.sup.8 .OMEGA..cm and contacts with a photosensitive layer of a photosensitive drum, an electrode which is electrically connected to the contact piled cloth and has an electric resistance lower than the predetermined electric resistance of the contact piled cloth, and D.C. power source and A.C. power source for supplying a voltage on the electrode to charge the photosensitive layer. The contact piled cloth is provided with a multitude of raised furs formed of artificial fibers with conductive particles dispersed therein.
