    摘要: A development method comprising the steps of forming a layer of a developer comprising a toner and a magnetic carrier on a developer transporting member containing a magnet therein by means of a developer regulating member, transporting the developer layer on the developer transporting member to a development region where the developer transporting member opposes an image bearing member, and applying an oscillating electric field to the development region for supplying the toner from the developer layer to the image bearing member, thereby developing an image. The magnetic carrier comprises a magnetic powder dispersed in a binder resin having an acid value of 0 to 20 KOHmg/g and has 5 to 30 wt % of magnetic powder present on the surface thereof.

    摘要: The present invention relates to a binder carrier, comprising at least magnetic particles and a binder resin, characterized in that the binder resin comprises a thermoplastic silicone-modified acrylic resin and an amino-group-containing resin. The binder carrier is capable of preventing carrier degradation caused by toner ingredients such as a charge-control agent and a post-processing agent for the toner. The binder carrier of the present invention has a long life with less susceptibility to degradation in charging performance, and makes it possible to quickly charge the toner sufficiently.
