A conductive polymer composition selected from the group consisting of

Conducting compositions

Electrical components comprising a ohmic contact-providing layer and a charge transport layer wherein the ohmic contact-providing layer comprises a fluorinated carbon filled fluoropolymer.

Ohmic contact-providing compositions

An apparatus for charging an ionographic member, comprising an electrically insulating substrate containing affixed thereto a plurality of electroded grooves each capable of retaining a single wettable fiber, thereby forming a collection of fibers in contact with the substrate; a resin layer that isolates said fibers from each other, and that adheres the fibers to the electroded grooves; providing an ionically conductive fluid to said collection of fibers; applying an electrical bias to said fibers thereby transporting ions through the fibers to the surface of said ionographic member and which ions charge said member.

Ionographic charging apparatus and processes

An electroluminescent (EL) device includes a polymeric tetraaryl substituted biphenyldiamine.

Electroluminescent device

A process for changing layered imaging members by the transfer of ions thereto which comprises contacting the imaging member with a liquid developer comprised of a nonpolar liquid, and a mixture of surfactants of an ammonium block copolymer first surfactant of the formula ##STR1## wherein X.sup.- is a conjugate base or anion of a strong acid; R is hydrogen or alkyl; R' is alkyl; R' is an alkyl group containing from about 6 to about 20 carbon atoms; and y and x represent the number average degree of polymerization (DP) wherein the ratio of y to x is in the range of from about 10 to 2 to about 1,000 to 200; and a second surfactant component of the formula ##STR2## wherein R.sub.1 is selected from the group consisting of hydrogen and alkyl, and n is 0 (zero), 1, 2, 3, or 4.

Charging processes with liquid compositions

A process for charging layered imaging members by the transfer of ions thereto from an ionically conductive medium.

Photoconductive charging processes

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.
