Abstract
The invention discloses a novel developing roller for a toner cartridge of a printer or a copying machine. The novel developing roller comprises a conductive rotating shaft, wherein a nonmetal conductive foaming layer is arranged outside the conductive rotating shaft; a conductive gum cover with the smooth and wearable outer surface is arranged outside the nonmetal conductive foaming layer. According to the developing roller, a conventional dense rubber layer is replaced by foaming materials, the conductive gum cover is sleeved outside the foaming materials, and the foaming materials and the conductive gum cover are low in cost. The novel developing roller is simple in process, energy-saving, environment-friendly, light in weight and convenient to carry.
Description
Technical field
The present invention relates to the digital printing field, especially a kind of novel developer roll for printer and copier toner.
Background technology
Toner cartridge is the core imaging device of laser printer and duplicating machine, and developer roll is one of them pith.During developer roll work, the surface is with electric charge, absorption carbon dust (effect is equivalent to the magnetic roller), when the print data of input after treatment, be converted into corresponding laser signal, by one group of prismatic refraction to toner cartridge (OPC) surface, thereby form charge latent image (concrete " image " or " literal " information that electric charge forms), when OPC rotation process developer roll, the latent image part is answered carbon dust from the developing roller surface Adsorption Phase, forms the carbon dust reality.
Developer roll structure from the inside to the outside is followed successively by at present: conduction rotating shaft, conductive rubber layer, conductive coating, conductive rubber layer is special rubber, high-grade have an ECO material, general is the materials such as EPDM, NBR, expensive, and rubber layer is closely knit and thick and heavy, and consumption is many, cause the cost of toner cartridge high, also indirectly increased the overall weight of toner cartridge.
Summary of the invention
For solving the problems of the technologies described above, the technical problem to be solved in the present invention provides that a kind of cost is low, energy-conserving and environment-protective, the printer of lightweight and the novel developer roll of copier toner.
The technical solution used in the present invention is: a kind of novel developer roll for printer and copier toner, comprise a conduction rotating shaft, described conduction rotating shaft is provided with a nonmetal conductive foaming layer outward, and described nonmetal conductive foaming layer is provided with the wear-resisting conduction gum cover of a smooth outer surface outward.
Described nonmetal conductive foaming layer is the hollow cylinder body structure, described hollow cylinder be set in the conduction rotating shaft on, described conduction gum cover is set on the hollow cylinder.
Described nonmetal conductive foaming layer is porose foaming layer or atresia foaming layer.
Described nonmetal conductive foaming layer is foamed plastic or bipeltate or the foamed rubber-plastic mixture that is doped with conductive materials.
Described bipeltate is a kind of and multiple combination in polyurathamc rubber, foaming ECO rubber, foaming EPDM rubber and the foaming NBR rubber.
Described conduction gum cover is plastics gum cover or rubber gum cover or the rubber and plastic mixture gum cover that is doped with conductive materials.
Described hollow cylinder both ends of the surface respectively are provided with an annular hard gasket, the external diameter of described annular hard gasket is less than or equal to the external diameter of hollow cylinder and greater than the external diameter of conduction rotating shaft, the longitudinal length of described conduction gum cover covers the conduction gum cover two end portions towards conduction rotating shaft and hot melt bending greater than the hollow cylinder body length on the described annular hard gasket.
Beneficial effect of the present invention:
Developer roll of the present invention adopts expanded material to replace traditional closely knit rubber layer, and expanded material outside the conduction gum cover of sheathed smooth abrasion-proof, expanded material and the cost of gum cover of conducting electricity are low, technique is simple, energy-conserving and environment-protective are lightweight, are easy to carry;
Nonmetal conductive foaming layer is hollow cylinder, and this hollow cylinder is set in the conduction rotating shaft, and the conduction gum cover is set on the hollow cylinder, so the developer roll assembly process is simple, has improved production efficiency;
Conduction gum cover two ends respectively are arranged with an annular hard gasket, make developer roll of the present invention possess the rigidity of traditional closely knit rubber developer roll, are difficult for shake or skew occur when toner cartridge is worked, and have guaranteed the development quality.
