Abstract
A toner and electrostatic development process involving electrostatic development without carrier is disclosed. The toner of the invention is effectively transferred from photoreceptors to plain paper after development. The toner is formed of a combination of an insulating toner and conductive toner that are not triboelectrically active with respect to each other.
