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.

Abstract: A method of treating a preformed flexible imaging belt including providing a rigid cylindrical support drum having a precisely predetermined outer circumference, a first end and a second end, providing a preformed flexible electrostatographic imaging belt, circumferentially expanding the belt with a flowing fluid under pressure until the circumference of the inner surface of the belt adjacent the first end of the drum is stretched to a new dimension of at least about 0.1 percent greater than the outer circumference of the rigid support drum while maintaining the belt below the elastic limit of the belt to smooth out physical defects, sliding the belt onto the drum from the first end toward the second end until substantially all of the belt encircles the outer surface of the drum, terminating the flow of the flowing fluid to allow the belt to contract onto the outer surface of the support drum, heating the belt to a treatment temperature of between about the glass transition temperature and about 10.degree.
