ABSTRACT:
Within an electrophotographic copier having a moving photoconductor member, a dry magnetic developing apparatus has an endless web for the purpose of transporting dry magnetic developer material from the supply to the developing zone. The web is constructed from a material formed of an inner electrically insulative base and with a textured, electrically conductive outer surface capable of picking up a supply of developer material. The dry developer material is then caused to tumble upon the web and through the gap defining the developing zone, under the influence of fixed magnets located within the developing apparatus. The tumbling action greatly extends the opportunity to provide toner to the charged image along the arcuate path which includes the development zone between the carrier web and the photoconductor.
