Abstract

The invention provides a conductive elastomer roller, and a manufacturing method and application thereof. The conductive elastomer roller of the invention comprises a sleeve and at least one elastic layer arranged on the outer circumference of the sleeve, wherein the elastic layer is formed by an elastomer composition which comprises a base material and a conductive agent; the base material comprises a solid rubber material, and has at least one first host material; the first host material is a rubber with Mooney viscosity of less than 40; and the mass content of the first host material in thebase material is no less than 5%. The material type and molding manner of the above-mentioned elastic layer of the conductive elastomer roller are not limited, and the conductive elastomer roller canbe processed in batch in a compression molding manner and has excellent overall performance.

Description

technical field [0001] The invention belongs to the technical field of image formation, and in particular relates to a conductive elastic body roller and its manufacturing method and application. Background technique [0002] With the development of miniaturization of laser imaging equipment, more and more laser printers adopt the printing mode without cleaning system. The specific structure of the process box used in this kind of printer is as follows figure 1 with figure 2 shown. Specifically, the process cartridge includes a developing frame a and a photosensitive frame b, and a developing element 13 is rotatably supported in the developing frame a, and a powder control unit 15 is arranged on the developing element 13; usually, a conductive elastomer roller is used as the developing element 13. It consists of a rotatable metal sleeve and a relatively fixed magnetic core. The magnetic core is located inside the sleeve. An elastic layer is provided on the surface of the ...
