An electrostatographic reproduction apparatus includes: a primary imaging member for producing an electrostatic latent image on a receiver, a development station for applying toner particles to the latent image to form a developed toner image on the receiver, a fuser assembly for fixing the developed toner image to form a fused toner image on the receiver, and a transport member for transporting the receiver to or from the fuser assembly. The transport member includes a substrate and an oil-absorbing layer that contains inorganic particles dispersed in an organic binder and is capable of absorbing release oil applied to the receiver bearing the fused toner image.

In a process for forming an amorphous TiOPc/TiOFPc pigment mixture containing a low concentration of TiOFPc, a mixture containing phthalonitrile and titanium tetrachloride is subjected to reaction conditions effective to form lightly chlorine-substituted crude crystalline Cl&#x2014;TiOPc. The lightly chlorine-substituted crude crystalline Cl&#x2014;TiOPc is combined with crude crystalline TiOFPc in a weight ratio from about 75:25 Cl&#x2014;TiOPc:TiOFPc to about 99.5:0.5 Cl&#x2014;TiOPc:TiOFPC to form a crude crystalline pigment mixture, which is treated under conditions effective to form a substantially amorphous pigment mixture of Cl&#x2014;TiOPc and TiOFPc. The substantially amorphous mixture can subsequently be converted to a nanocrystalline Cl&#x2014;TiOPc/TiOFPc pigment composition containing a low concentration of TiOFPc.

A multi-active electrophotographic charge generation element comprises a conductive support, a charge generation layer (CGL) disposed on the conductive support, and a charge transport layer (CTL) disposed on the charge generation layer. The charge generation layer (CGL) includes a charge-generation material comprising an aggregated or crystalline form of a first dye or pigment and a first polymeric binder. The charge transport layer (CTL) comprises at least one charge-transport agent, a second dye or pigment having absorption in a selected spectral region that at least partially overlaps the absorption of a dissolved non-aggregated or non-crystalline form of the first dye or pigment, and a second polymeric binder. The second dye or pigment in the charge transport layer absorbs radiation in the selected spectral region that is incident on the charge transport layer, thereby shielding the charge generation layer from that radiation and mitigating visible radiation-induced photofatigue.
