ABSTRACT:
A thin insulative film is applied to be in direct contact with a surface carrying an electrostatic image which has a potential sufficient for adherence by induction of toner to the insulative film but insufficient to discharge when in contact with or upon separation of the toned insulative film. When the surface is photoconductive, it is exposed before or after contact with the insulative film to a pattern of discharging radiation to form an electrostatic image thereon. As one form of image development, toner is applied to the insulative film while in direct contact with the imaged surface. Thereafter, the toner image may be transferred to a support member. Toning and toner transfer is repeated without further charge and without further exposure.
