Abstract: Plasticizers in a charge transfer layer to reduce surface cracking and crazing having a hydrocarbon chain, attached to a hindered phenol containing triazole or triazine moiety. Plasticizers found useful for this application can be used in a concentration (by weight of the charge transfer layer) in the order of magnitude of 10% to about 25%. The plasticizer additive may also be used in combination with other known plasticizers such as those containing a 2-ethylhexyl group.

Abstract: The present disclosure relates to an electrophotoconductive element comprising a conductive substrate, a charge generation layer including a charge generating compound and a charge transport layer. The charge generation layer includes a first polymer resin and second polymer resin to provide a blend including the charge generating compound. The first polymer resin may therefore indicate an energy at a half charge potential E0.5(POLYMER) upon exposure to light at a wavelength of about 350-500 nm. The blend then also indicates an energy at half charge potential E0.5(BLEND) upon exposure to light at a wavelength of about 350-500 nm. The second polymer resin of the blend is therefore selected to provide that E0.5(BLEND)

Abstract: The present disclosure relates to incorporation of boron nitride in the charge transport layer of a photoconductor. The boron nitride may have an aspect ratio of greater than 1.0, a D50 mean particle size of less than about 10.0 μm and be present at about 5.0% (wt) or less in the charge transport layer. The cartridge may also include toner particles wherein the toner particles have a size range of about 1-25 μm and an average degree of circularity of about 0.90-1.0. The photoconductor containing boron nitride when used in an electrophotographic printer may then provide acceptable dark decay and/or photoinduced decay (PID) curves relative to photoconductors that do not contain boron nitride along with improved resistance to toner filming.

Abstract: A process for preparing fuser belts in electrophotographic devices is disclosed. In this process the belt is coated, preferably using a vertical dip coating technique, with an aqueous solution containing a fluorocarbon polymer, such as Teflon, and a water-soluble polymer additive. Preferred additives include pectin, polyacrylic acid, and pectin/polyacrylic acid mixtures. This method provides efficient and effective vertical dip coating of the topcoat onto the fuser belt, particularly in terms of the uniformity of the coating, the stability of the coating dispersion, and the minimization of cracking when the coating is dried and sintered at high temperatures.
