Abstract
The utility model relates to a developing roller for a laser printer, which comprises a roller core (4), an electric conduction adhesive layer (3) which is arranged on the roller core (4), a conductive rubber elastic body (2) which is arranged on the electric conduction adhesive layer (3), and a conductive coating (1) which is arranged on the electric conduction adhesive layer (3), wherein the roller core (4) is a metallic conduction base. The utility model of which the density is reduced following the change of corona is suitable for a laser printer, or an integral computer, or a copier, or a digital camera with monocomponent image-forming principle. The utility model has the characteristics of small density, homogeneous volume resistivity, no pollution to a photoconductor, high printing resolution, sharp and favorable effect of printing, and long service life.
Description
Technical field: the utility model relates to a kind of laser printer developing roller, and this developer roll is the critical component of laser printer.
Background technology: in the prior art, the roller core skin of laser printer developing roller is made by rubber-plastics material.Owing to its structural reason, exist the shortcoming that imaging is clear inadequately, resolution low and serviceable life is short.
Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of resolution height, printing effect new pattern laser printer developer roll clearly is provided.For achieving the above object, the utility model adopts following technical proposals: the laser printer developing roller, comprise roller core (4), and roller core (4) is provided with conductive adhesive (3), conductive adhesive (3) is provided with conductive rubber elastic body (2), and conductive rubber elastic body (2) is provided with conductive coating (1).Above-mentioned roller core (4) is the metallic conduction matrix.
The utility model dwindles with the variation density of corona, the laser printer of applicable single component image-forming principle, all-in-one, duplicating machine, digital camera.This product has that density is little, specific insulation evenly, does not pollute photoreceptor, the characteristics of print resolution height, clear, effective, long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, the laser printer developing roller comprises roller core 4, roller core 4 is provided with conductive adhesive 3, conductive adhesive 3 is provided with conductive rubber elastic body 2, and conductive rubber elastic body 2 is provided with conductive coating 1, is in outermost conductive coating 1 by the environment-friendly type macromolecule material.
Principle of work: the utility model is to utilize the electronic imaging developing technique to print.Its main effect is the imaging drum to be gone up established carbon dust image duplicate.On the conductive elastic rubber developer roll, add the 1-2KV DC voltage or DC stacked voltage contacts with carbon dust with given pressure, can obtain the current potential same, do not make carbon dust and photosensitive surface directly charged because shielding not, so title chemical development with charger unit.
Claims (1)
1, a kind of laser printer developing roller, comprise roller core (4), it is characterized in that: roller core (4) is provided with conductive adhesive (3), conductive adhesive (3) is provided with conductive rubber elastic body (2), conductive rubber elastic body (2) is provided with conductive coating (1), and above-mentioned roller core (4) is the metallic conduction matrix.
