ABSTRACT:
A multi-layered organic electrophotographic photoconductor exhibits superior stability in mass production and excellent adhesion ability with two layers contacting the charge generation layer and is free of contamination of the coating liquid for a charge transport layer during a dip-coating process due to dissolution of the charge generation layer. The multi-layered organic electrophotographic photoconductor includes a conductive substrate and layers including an undercoat layer containing a thermosetting resin, a charge generation layer containing a charge generation material and an organic binder resin, and a charge transport layer laminated sequentially on the substrate, wherein polydispersity defined by a ratio of a weight average molecular weight to a number average molecular weight of the organic binder resin is at least 4.0, and the weight average molecular weight is at least 7.0×104in a distribution of a polystyrene-converted molecular weight obtained by gel permeation chromatography.
