    摘要： A dry electrostatographic process involving the development of the latent image using a semi-dry developer having a solids content ranging from about 50% to about 99% by weight based on the weight of the semi-dry developer, and wherein the semi-dry developer is prepared by a developer preparation process comprising: (i) removing liquid from a liquid developer in an effective amount to yield the semi-dry developer; or (ii) adding a liquid additive to a dry developer containing toner particles ranging in size of from about 1 to 7 microns in an effective amount to yield the semi-dry developer.

    摘要： A process for fabricating a substrate includes the steps of (a) immersing a molding article having an electrically conductive molding surface in an electrodeposition liquid comprising polymer particles and a nucleating material; (b) electrodepositing a coating on the molding article; and (c) coalescing the coating to form a substrate containing the nucleating material. The process may further include exposing the substrate to an electroless metal plating bath to form a metal layer on the substrate. A process for fabricating an electrostatographic imaging member includes electrolessly depositing metal on a substrate. A process for fabricating a belt comprises electrolessly depositing metal on an endless substrate. An electrostatographic imaging member comprises a substrate including polymer and nucleating material and a metal layer. An endless belt includes polymer and nucleating material.

    摘要： Polymer films are formed by electrocodeposition of solutions containing a dispersion of charged particles of a first polymer and charged particles of a second polymer. Microheterogeneous films are obtained having micro-domains of a minor component polymer dispersed in the major component polymer. Processes for preparing dispersions for electrocodeposition are also provided In a first process, two polymers are dissolved in a common solvent and then dispersed as small charged particles in another solvent which is a precipitant for both polymers. In another process, a dispersion of a first polymer is prepared by adding a solution of the first polymer to a dispersant solvent, and then a solution of a second polymer is dispersed in the dispersion of the first polymer. In another process, a solution of the second polymer is added to a dispersion of the first polymer which contains only a single non-solvent for the second polymer. In yet another process, a dispersion of the first polymer in a first solvent system is mixed directly with a dispersion of a second polymer in a second solvent system, resulting in a dispersion of the first and second polymers in a resulting solvent system of the first and second solvent systems. In yet another process, a block copolymer composed of two blocks is dissolved in a solvent, and then dispersed in a non-solvent to form the dispersion.

    摘要： An imaging apparatus comprises an imaging member, a means for generating an electrostatic latent image on the imaging member, a means for developing the latent image, an intermediate transfer element having a charge relaxation time from about 3.times.10.sup.-1 seconds to about 2.times.10.sup.2 seconds to which the developed image can be transferred from the imaging member, and a means for transferring the developed image from the intermediate transfer element to a substrate. Also disclosed is an imaging process which comprises generating an electrostatic latent image on an imaging member, developing the latent image, transferring the developed image to an intermediate transfer element having a change relaxation time from about 3.times.10.sup.-1 seconds to about 2.times.10.sup.2 seconds, which enables the transfer with very high transfer efficiency of the developed image from the intermediate transfer element to substrate.
