    摘要： A device for applying an electrical charge to a charge retentive surface by transporting ions in a fluid media and transferring the ions to the member to be charged across the fluid media/charge retentive surface interface. The fluid media is positioned in contact with a charge retentive surface for depositing ions onto the charge retentive surface. In one specific embodiment, the fluid media is a ferrofluid material wherein a magnet is utilized to control the position of the fluid media, which, in turn, can be utilized to selectively control the activation of the charging process.

    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： An apparatus and method that insures an even distribution of liquid in an aquatron charging device across the entire length of the device. This enables uniform charging across the width of the photoreceptor. The present invention fills and pressurizes a porous tube with a liquid. The liquid evenly exudes from the pores along the entire length of the porous tube. A hydrophilic liquid retentive foam which contacts the photoreceptor surface is wrapped snugly around the tube. The conductivity and overall rate of dispensation of liquid is controlled by the pressure differential across the porous tube.

    摘要： Electrostatographic carrier materials having low bulk densities and high magnetic permeabilities are obtained by impregnating low density porous silicaceous particles with a magnetic or magnetically-attractable transition metal or metal oxide thereof. The low density magnetic composite carrier particles are prpepared by the thermal decomposition of transition metal carbonyls in the presence of the silicaceous particles with a suitable suspending medium. Air and moisture are excluded from the reaction vessel and the contents are heated with agitation so that the carbonyl boils and the mixture is refluxed until the temperature rises to that of the suspending medium whereupon impregnation of the silicaceous particles with elemental metal and/or metal oxide is complete. The mixture is cooled, the beads washed, air-dried, and recovered. When mixed with toner particles the aforementioned carrier materials experience significantly reduced toner impaction levels.
