Abstract
A method for making a photoconductor for electrophotography can comprise depositing a charge generating layer on an electrode; depositing a charge transfer layer on the charge generating layer, where a plurality of charge transfer molecules are disposed within the charge transfer layer; depositing a film of non-conducting material onto the surface of the charge-transfer layer; heating the film and the surface to cause a subset of the charge transfer molecules to move into the non-conducting material, creating in the film a conducting sub-layer and an insulating sub-layer, where the insulating sub-layer is substantially free of charge transfer molecules.

A method of making a photoreceptor for electrophotography, comprising:
- depositing a charge generating layer on an electrode;
- depositing a charge transfer layer on the charge generation layer, said charge transfer layer having a plurality of charge transfer molecules disposed therein, and said charge transfer layer having a surface;
- depositing a film comprising a non-conducting material onto the surface;
- heating the film and the surface for a time and at a temperature, wherein the heating causes a subset of the charge transfer molecules to move into the non-conducting material to create within the film a conducting sub-layer adjacent to the charge transfer layer and an insulating sub-layer situated distally with respect to the charge transfer layer, and wherein the insulating sub-layer is substantially free of charge transfer molecules.
A photoconductor for electrophotography, comprising:
- a charge generating layer disposed on an electrode;
- a charge transfer layer disposed on the charge generating layer;
- a film of non-conducting material disposed on the charge transfer layer and comprising a conducting sub-layer adjacent to the charge transfer layer and an insulating sub-layer situated distally to the charge transfer layer;
- a plurality of charge transfer molecules distributed within the charge transfer layer and the conducting sub-layer while being substantially absent from the insulating sub-layer.
