An electrographic imaging member including: (a) a flexible dielectric imaging layer having a uniform thickness of between about 10 micrometers and about 50 micrometers and including a thermoplastic film forming polymer, and (b) a flexible supporting substrate having an electrically conductive surface, the substrate including: (1) a single substrate layer having a uniform thickness of between about 25 micrometers and about 200 micrometers and including a thermoplastic film forming polymer or (2) dual layers comprising an inner substrate layer and an outer substrate layer, the inner substrate layer having a uniform thickness of between about 25 micrometers and about 200 micrometers and including a thermoplastic film forming polymer and the outer substrate layer having a uniform thickness of between about 10 micrometers and about 50 micrometers and including a thermoplastic film forming polymer, wherein the linear tension force measured in any direction along the plane of the dielectric imaging layer is substantially the same as the linear tension force measured along the plane of the outer substrate layer in the same direction as the direction selected for measuring the linear tension force in the dielectric imaging layer to impart a flat shape to the electrographic imaging member. A method of using this member in an electrographic imaging process is also disclosed.
