A composite organic photoconductor for electrophotography is described. The composite photoconductor includes a conductive support, a charge generation layer and a particulate charge transport layer disposed between the conductive support and the charge generation layer. The charge transport layer is formed from a first colorant composition comprising a particulate pigment embedded in a polymeric matrix. The charge generation layer is formed from a second colorant composition which comprises either a pigment or a dye. The charge transport layer has an infrared absorption maximum of about 740 nm, and the charge generation layer has an infrared absorption maximum greater than about 770 nm. The composite organic photoconductor exhibits both good electrophotographic response and superior thermal stability over a range of operating conditions, and is thus useful in a number of electrophotographic processes such as those employing charging, exposing and developing operations to form images.
