Embodiment

[0105] Get a seamless polyimide ITB that produces substandard print quality. This seamless polyimide ITB has been used in electrophotographic machines. The ITB is then cleaned with isopropyl alcohol to remove any toner residue on the surface, and allowed to air dry. The seamless polyimide ITB was coated with a coating liquid comprising polyvinylidene fluoride (PVDF) and carbon black by a draw bar coater. PVDF is a specialty plastic material in the fluorinated polymer family, commonly used in applications requiring high purity, strength and resistance to solvents, acids, bases and heat. It has a relatively low cost compared to other fluorinated polymers.

[0106] The details of the coating liquid included forming 0.4 g of a N-methylpyrrolidone (NMP) dispersion containing 18.7% by weight of carbon black (Special Black4). Mix the dispersion with 1.5 g 301F PVDF resin was mixed in 13.5 grams of N,N'-dimethylformamide (DMF). The mixture was coated by a 2.0-mil Bard bar onto a...

Abstract

A method for repairing an intermediate transfer member and a repaired intermediate transfer member are disclosed herein. The method includes releasing soil from an outer layer of the intermediate transfer member. A mixture of polymer, conductive particles and solvent is coated on the outer surface of the seamless intermediate transfer member. The mixture is heated to form a layer on the outer surface of the intermediate transfer belt. An apparatus for repairing an intermediate transfer member is also described.

Description

technical field [0001] The present invention relates to an image forming device and an intermediate transfer member. Background technique [0002] An image forming apparatus that forms a color or black-and-white image by electrostatically transferring toner using an intermediate transfer member is known. When an image is formed on paper in a color image forming apparatus using such an intermediate transfer member, images of four colors of yellow, magenta, cyan, and black are usually first sequentially transferred from an image carrier such as a photoreceptor And superimposed on the intermediate transfer member (primary transfer). The full-color image is then transferred to paper in one step (secondary transfer). In a black-and-white image forming device, a black image is transferred from a photoreceptor and superimposed on an intermediate transfer member, and then transferred onto paper. [0003] Some intermediate transfer members are in the form of seamless belts. These...
