ABSTRACT:
The self-stripping action of a copy sheet from an imaging suface after transfer in electrostatographic copying is substantially increased by slightly curving the imaging surface transverse their mutual direction of movement to provide a slight corresponding crown in the copy sheet on the imaging surface at the stripping area where the imaging surface is curved away from the path of the copy sheet in their direction of movement. Examples of the imaging surface are a substantially cylindrical photoreceptor surface with a uniform slight continuous crown, or a flexible belt slightly deformed over a crowned support roller.
