    摘要: An apparatus for applying an electrical charge to a charge retentive surface by transporting ions through an ionically conductive liquid and transferring the ions to the member to be charged across the liquid/charge retentive surface interface. The ionically conductive liquid is contacted with the charge retentive surface for depositing ions onto the charge retentive surface via a wetted donor blade supported within a conductive housing, wherein the housing is coupled to an electrical power supply for applying an electrical potential to the ionically conductive liquid. In one specific embodiment, the charging apparatus includes a support blade for urging the donor blade into contact with the charge retentive surface and a wiping blade for wiping any liquid from the surface of the charge retentive surface as may have been transferred to the surface at the donor blade/charge retentive surface interface.

    摘要: Electrostatographic carrier coating compositions which provide porous carrier cores with coatings that are more uniform in thickness and complete in integrity are obtained by employing a thixotropic lacquer. The nature of the thixotropic lacquer is such that its viscosity is low under high shear rates, but high under low shear rates as found during the spreading and penetration of the lacquer on the carrier cores.

The ionically conductive liquid is contacted with the charge retentive surface for depositing ions onto the charge retentive surface via a wetted donor blade supported within a mechanically sealable housing adapted to permit movement of the wetted donor blade from an operative position in contact with the charge retentive surface, to a nonoperative position stored within the housing to prevent loss of the ionically conductive liquid in its liquid or vapor form so as to extend the functional life of the apparatus. In one specific embodiment, a wiper blade may be provided for removing any liquid droplets from the surface of the photoreceptor as may have been transferred at the donor blade/charge retentive surface interface.
