Electrostatographic imaging member process

A flexible belt comprising a flexible support layer, at least one coating comprising a film forming polymer, and a seam having a bent shape extending from one edge of the belt to the opposite edge of the belt. The flexible electrostatographic imaging belt may be fabricated by providing a sheet having two parallel sides and two opposite ends having matching bent profiles, the sheet having a first major exterior surface opposite and parallel to a second major exterior surface, overlapping an edge of the first major exterior surface adjacent one of the ends onto an edge of the second major exterior surface adjacent the other one of the ends to form a overlapped joint in which the bent profiles of the opposite ends match, and permanently securing the ends to each other to form a seam having a bent shape. This seamed flexible electrostatographic imaging belt may be used in an electrostatographic imaging process.

Flexible belts having a bent seam

An electrostatographic imaging process is disclosed which includes providing a flexible electrostatographic, particularly electrophotographic, imaging belt including a substrate layer, a charge generating layer, charge transport layer, and two parallel longitudinal edges, the imaging belt having a charge transport layer tension strain of less than about 0.05 percent across the width of the belt, mounting the imaging belt on a plurality of spaced apart support rollers, transporting the belt around the support rollers, repeatedly applying a cross belt compression strain distributed in an arcuate gradient of increasing intensity from the longitudinal centerline of the belt to each of the edges of the belt, the strain applied at each of the edges of the belt repeatedly peaking to an intensity at the longitudinal edges of at least about 0.6 percent greater than the strain applied to the centerline of the belt, forming an electrostatic latent image on the belt, developing the electrostatic latent image with toner to form a toner image corresponding to the latent image, transferring the toner image to a receiving member, and repeating the forming, developing and transferring steps at least once. The flexible electrostatographic imaging belt may be fabricated without an anti-curl layer in a continuous process.

Imaging process using flexible electrostatographic imaging member

A method of fabricating a cylindrical device comprising having at least one distinct outer layer comprising providing a preformed rigid cylindrical support drum having a predetermined outer circumference, a first end and a second end, providing a flexible belt having an inner circumference at least about 0.05 percent smaller than the outer circumference of the support drum, circumferentially expanding the belt with a flowing fluid under pressure until the circumference of the inner surface of the belt adjacent the first end is stretched to a new dimension at least about 0.1 percent greater than the outer circumference of the support drum while maintaining an elongation strain less than the elastic limit of the belt, sliding the belt onto the support drum from the first end toward the second end of the support drum until substantially all of the belt encircles the outer surface of the support drum and terminating the flow of the flowing liquid to allow the belt to contract onto the outer surface of the support drum. The fluid may either be a gas or a liquid. The cylindrical device fabricated by this process is preferably an electrostatographic imaging member. This electrostatographic imaging member may be utilized in an electrostatographic imaging process.

Flexible tubes supported on rigid drum

A corona generating device of the type having a conductive shield partially surrounding a corona discharge electrode is provided with heating element. The heating element raises the surface temperature of the conductive shield to reduce or eliminate the adsorption of corona effluents and thereby minimize or prevent copy quality defects.
