Title:
静電潜像現像装置の製造方法
Document Type and Number:
Japanese Patent JP4335989
Kind Code:
B2
Abstract:
An apparatus and method for non-interactive, dry powder development of electrostatic images comprising: an image bearing member (12) bearing an electrostatic image; two component developer comprising toner and permanently magnetized carrier beads, the carrier having average diameter 2a and magnetization Mb a developer transporting member (100) having a thickness t for transporting a developer layer of the two component developer, the layer spaced close to and out of contact with the image bearing member, and wherein the developer layer is substantially without chains of carrier beads, a multipole magnet member (400) disposed in close proximity behind the transporting member and moving relative to it so as to sweep poles across its surface, the magnet member having a periodic magnetization of spatial frequency k and a peak magnetization M0 wherein a, Mb, t, k, and M0, are chosen such that Mb is sufficiently large to prevent the escape of developer, and a quantity
