Abstract

The invention discloses a development magnetic core for a digital duplicator and a laser printer. Along a development magnetic core revolution direction, the cross section of the development magnetic core is provided with raised parts which have the number the same as the number of magnetic poles and extend outward along the center of the cross section of the development magnetic core so that the strip-shaped raised parts parallel to the axis of the development magnetic core are formed along the length direction of the development magnetic core, and each one of the raised parts is provided with one magnetic pole. Through the above scheme, interference of magnetic poles of the oriented magnetic field is reduced, the magnetic pole size and magnetic pole included angle can be accurately designed, materials are saved, a cost is reduced, magnetic pole action ranges can be optionally adjusted according to functions of the magnetic poles, better matching with other parts can be provided, printing and reprography quality can be improved, machine weight is reduced and installation and use are convenient.

Description

technical field [0001] The invention belongs to the technical field of electronic imaging, and relates to copiers and laser printers. More specifically, the invention relates to developing magnetic cores for digital copiers and laser printers. Background technique [0002] As shown in the accompanying drawings of this manual figure 1 As shown, in the prior art, the cross-sections of the developing magnetic cores 1 used in digital copiers and laser printers are all circular. [0003] This structure has the following disadvantages: one is waste of material, and the other is that the magnetic angle of the magnetic poles is not precise enough and difficult to control. Contents of the invention [0004] The invention provides a developing magnetic core for a digital duplicator and a laser printer, and aims at saving materials, reducing costs and improving the quality of use. [0005] In order to achieve the above object, the technical scheme that the present invention takes i...
