Abstract: An intermediate toner transfer element comprises a substrate coated with a volume grafted elastomer which is a substantially uniform integral interpenetrating network of a hybrid compsn. of a fluoroelastomer and a polyorganosiloxane, the volume graft having been formed by dehydrofluorination of the fluoroelastomer by a nucleophilic dehydrofluorinating agent, followed by addition polymerisation by the addition of an alkene or alkyne functionally terminated polyorganosiloxane and a polymerisation.

Abstract: An electrophotographic imaging system utilizing a member comprising at least one photoconductive layer and an overcoating layer comprising a film forming continuous phase comprising charge transport molecules and finely divided charge injection enabling particles dispersed in the continuous phase, the insulating overcoating layer being substantially transparent to activating radiation to which the photoconductive layer is sensitive and substantially electrically insulating at low electrical fields.

Abstract: The development apparatus of an electrostatographic printer has a donor roll (74) formed by mixing resin particles with conductive particles and subsequently extruding or centrifugally casting the mixture into a cylindrical shell. The shell is cut to the desired length and journals are attached to each end of the shell. The resin particles are thermoset particles preferably phenolic resin particles, and the conductive particles are preferably graphite particles.

Abstract: A thick organic ambipolar layer on a photoresponsive device is simultaneously capable of charge generation and charge transport. In particular, the organic photoresponsive layer contains an electron transport material such as a fluorenylidene malonitrile derivative and a hole transport material such as a dihydroxy tetraphenyl benzadine containing polymer. These may be complexed to provide photoresponsivity, and/or a photoresponsive pigment or dye may also be included.

Abstract: An ionographic imaging member containing a conductive layer (67) and a uniform and continuous dielectric imaging layer (66) free of voids, the imaging layer having a dielectric constant of from about 1.5 to about 40 and a thickness of at least about 45 micrometers, the thickness divided by the dielectric constant having a value of from about 30 to about 60 micrometers. This member may be used in an ionographic imaging process.
