    摘要： This invention pertains to a sawtooth AC charger (10) in which an AC voltage signal applied to sawtooth blades (12) has a duty cycle greater than 50%. Duty cycles above about 70% increase the uniformity of negative charging without significantly increasing the peak voltage to the sawtooth blades.

    摘要： An electrographic primary imaging member upon which an electrographic image may be written includes a support member; a charge retention layer for the electrographic image; a compliant layer being formed on the support member as an intermediate layer between the charge retention layer and the support member, the compliant layer being formed of a material having a Young's modulus of between about 0.1 MPa and about 100 MPa and a thickness of between at least 1 mm and about 20 mm; and the charge retention layer being a dielectric and being substantially thinner than the compliant layer and being supported on the support member and having a Young's modulus of greater than that of the compliant layer and at least about 80 MPa. The imaging member may form part of an electrographic recording apparatus wherein the electrographic image is developed and transferred to a receiver sheet or transferred to an intermediate transfer member from which it is then transferred to a receiver sheet.

    摘要： This invention pertains to an AC charger (10) in which an AC voltage waveform applied to a corona wires (12) has a duty cycle of between 50% and 90%. This increases the efficiency of the charger without increasing the signal-to-noise ratio. In one embodiment, the AC voltage waveform is asymmetric.

    摘要： 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.

    摘要： Toner images are formed electrophotographically on a photoconductive imaging member and electrostatically transferred to a receiving surface. Electrostatic transfer is improved with a photoconductive image member having a compliant layer with a Young's modulus less than 5.times.10.sup.7 Pascals backing a thin photoconductive layer with a Young's modulus greater than 10.sup.8 Pascals. Preferably, the compliant layer is not more than 30 microns from the surface of the imaging member.
