    摘要： A flexible electrostatographic imaging belt having two parallel sides and a non imaging seam region extending substantially from one of the sides to the other side, the non-imaging seam region having a leading edge, a trailing edge and a seam within the non imaging seam region, the leading and trailing edges being perpendicular to the two parallel sides of the imaging belt, the belt comprising a substrate layer, a reflective electrically conductive layer, at least one imaging layer, an imaging region extending around the belt from adjacent the leading edge of the seam region to adjacent the trailing edge, the imaging region adapted to reflect monochromatic infrared radiation and a permanent localized solid attribute at a predetermined location in the non imaging seam region, the attribute adapted to reduce by at least about 50 percent direct reflection by the seam itself of a beam of monochromatic infrared radiation originally directed at the attribute. This belt is used in imaging apparatus and imaging processes.

    摘要： 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. C. above the glass transition temperature of the substrate or the imaging layer, the treatment temperature being the higher of these two glass transition temperatures, until the belt relaxes onto the outer circumference of the rigid drum and is substantially free of any tendency to contract back to the original circumference of the inner exposed surface prior to circumferentially expanding the belt, cooling the belt to ambient room temperature, and removing the belt from the drum, the belt having a new inner circumference substantially identical to the precisely predetermined outer circumference of the rigid cylindrical support drum.
