ABSTRACT:
A weak electrostatic image on an imaging member is amplified by first toning it with a charge injection toner. The imaging member is recharged without fusing the toner image to a charge of the same polarity as the first charge but substantially higher potential. The excess charge over the first charge injects through the toner to create an amplified electrostatic image that can be toned.
