Apparatus for developing electrostatic latent image

摘要

An apparatus for developing an electrostatic latent image formed on a charge retaining member is provided. The apparatus includes a magnetic conveyor having a magnet roller and a non-magnetic sleeve and applies a magnetic two-component developer comprising a toner and a magnetic carrier to the latent image while it conveys the developer, thus forming a toner image. A tuft of developer carried by the non-magnetic sleeve is brought into contact with a thin uniform layer of toner formed on a toner supply roller to cause the toner to be transferred into the developer under the action of a magnetic or an electrostatic attraction.
