Abstract

A charging device which includes a sheet-like charging member to be brought into contact with a charge target member. The charging member being composed of at least an insulating layer and a resistance layer. The charging device further includes at least one voltage application device which applies a DC voltage to the resistance layer of the charging member. The resistance layer has a down stream portion which protrudes from the insulating layer, which is arranged at the side of the resistance layer of the charge target member. The down stream portion may take on various shapes which uniformly apply a charge to the charge target member. The charging member may further include another resistive layer which has a second voltage applied thereto, wherein the other resistive layer is mounted on the other side of the insulating layer and contacts the charge target member and securely holds the charging member in contact with the charge target member.
