摘要: 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.

摘要: 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.

摘要: A flexible imaging member which does not require the use of an anti-curl back coating is disclosed herein. The flexible imaging member has a layer comprising two charge transport molecules dispersed in a film-forming polymer binder and an overcoat layer. The first charge transport molecule is a biphenyl amine, terphenyl diamine, or bis(triarylamine) stilbene. The second charge transport molecule is a bis(triarylamine), tri-p-tolylamine, or triphenylamine. The weight ratio of second charge transport molecule to first charge transport molecule is from about 90:10 to about 66:34. Trifluoro acetic acid is also added to the layer containing the charge transport material.
