    Abstract: There is provided a photoconductive member comprising a conductive support and disposed thereon a charge generating layer. The charge generating layer comprises a first polymer binder and a perylene-tetracarbonic acid amide pigment having blue wavelength photosensitivity of the following formula: wherein each of R1, R2, R3, R4, R5, R6 and R7 are the same or different and are independently selected from the group comprising hydrogen, alkyl, aryl and halogen. A charge transport layer is disposed on the conductive support and comprises tri-p-toylamine and 1,-1-bis(N,N-ditoyl-4-aminophenyl)cyclohexane in a second polymer binder.

    Abstract: The present disclosure relates to a magnetic toner composition. The toner composition includes one or more resins, and spherical ferromagnetic nanoparticles. Also provided is a process for preparing these toners including ferromagnetic nanoparticles. In embodiments, the aggregation of the toner is conducted at a pH greater than about 7, without the use of a coagulant. Additionally, in embodiments, freezing (stopping particle growth) and coalescence of the toner particles may be conducted at a pH greater than about 9. In yet other embodiments, the process may be conducted under an inert gas such as argon to avoid oxidation of the ferromagnetic nanoparticles during toner preparation.

    Abstract: Processes for making organic pigments useful in imaging members, specifically for pigments that after further polymorphic conversion may be used in a charge generating layer of an imaging member. More specifically, there are described processes for producing titanyl phthalocyanine (TiOPc) in high yields using tetrahydronaphthalene as reaction solvent, such as TiOPc Type I. This pigment can be successfully converted to a high sensitivity crystal form useful as charge generating pigment in an imaging member.
