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.
