    Abstract: Photoconductive imaging members comprise a symmetrical dimeric perylene as a charge generator, where the perylene is of formula (I): R = H, (cyclo)alkyl, oxa-alkyl, substituted alkyl, (substituted) aryl, or (substituted) aralkyl; and X = symmetrical bridging moiety, N-N when n is 0, (substituted) alkylene, cycloalkylene, (substituted) arylene or (substituted) aralkylene. Also claimed are: (i) a photoconductive imaging member (A); (ii) an imaging method comprising the formation of a latent image on the photoconductive imaging member; (iii) an imaging method comprising the formation of a latent image on the photoconductive imaging member (A); (iv) symmetrical perylenes (I); and (v) a process for the preparation of dimeric perylenes comprising reacting a perylene mono-imido anhydride with a symmetrical diamine.

    Abstract: A process for the preparation of toner compositions which comprises dissolving a polymer, and optionally a pigment in an organic solvent; dispersing the resulting solution in an aqueous media containing a surfactant, or mixture of surfactants; stirring the mixture with optional heating to remove the organic solvent thereby obtaining suspended particles of about 0.05 micron to about 2 microns in volume diameter; subsequently homogenizing the resulting suspension with an optional pigment in water and surfactant; followed by aggregating the mixture by heating thereby providing toner particles with an average particle volume diameter of from between about 3 to about 50 microns, and preferably from about 3 to about 21 microns, when said pigment is present.
