Abstract
A method to remove during fabrication of a flexible electrostatographic imaging member, the curl from a curled layered member having a top surface and a bottom surface and comprised of a substrate and a thickest coated layer including: (a) heating a section of the curled layered member to at least the glass transition temperature of the thickest coated layer, thereby defining a heated layered member section containing a thickest coated layer section and a substrate section; (b) compressing the top surface and the bottom surface of the heated layered member section to expand the thickest coated layer section beyond the dimensions of the substrate section; and (c) cooling the heated layered member section such that the expanded thickest coated layer section shrinks to about the dimensions of the substrate section.
