    • Composites comprising polymeric binders and phthalocyanine pigments to form a single layer positive organic photoconductor are provided for use in electrophotography. The polymeric binders comprise an aliphatic polymer or copolymer having a saturated ring for each repeat unit either included in the polymer chain or pendant therefrom and about 4 to 35% of functional groups such as -OH, -SH, >N-, >NH, and -NH 2 per repeat unit. The saturated ring portion, being essentially non-polar, or at least less polar than an unsaturated ring, maintains the specific morphology of the phthalocyanine pigments commonly employed in positive charge organic photoconductors (OPCs) and results in a stable dispersion required for the stable performance of the OPC. Keeping the functional groups listed above to less than about 35% ensures that the photoresponse is not reduced to an unacceptable level. Heating of the composite is used to control the concentration of the functional groups. One or more separate thermal carrier generation control agents comprising compounds containing the functional group(s) may be used to provide part or all of the functional groups in the composite.

    • An inverse dual-layer organic photoconductor ( 10 ) comprising a charge generation layer (CGL) ( 12 ) formed on top of a charge transport layer (CTL) ( 14 ), in turn formed on a substrate ( 16 ) such as a web (drum) or subbing layer, is disclosed, in which the CGL ( 12 ) includes a flexible polymer having a glass transition temperature (T g ) of less than about 120°C as the binder for a charge generation species and in which the CTL ( 14 ) includes a rigid polymer having a T g of greater than about 120°C as the binder for a charge transport species. The CTL ( 14 ) is coated onto the substrate ( 16 ), using a non-chlorinated solvent. The CGL ( 12 ) is coated onto the CTL ( 14 ), also using a non-chlorinated solvent, under conditions so as to form a diffused region ( 24 ) at the boundary ( 22 ) of the CGL ( 12 ) and CTL ( 14 ). This type of photoconductor ( 10 ) yields extremely low noise, exceptionally high-speed and excellent stable charging/discharging performance in the xerography process at room temperature and elevated temperature.
