摘要： An apparatus for developing in a development zone a latent image recorded on a surface, including; a housing defining a chamber storing at least a supply of toner therein. A donor roll disposed of at least partially in the chamber of said housing and spaced from the surface. The donor roll is adapted to rotate about a longitudinal axis to transport toner to the development zone in a region opposed from the surface. An elongated electrode member is mounted stationarily in the development zone and extending in a direction transverse to the longitudinal axis. The electrode member includes a flexible thin sheet having a plurality of elongated wires with adjacent wires which are spaced from and substantially parallel to one another. The electrode member is positioned in the development zone and spaced between the surface and said donor roll. The electrode is electrically biased to detach toner from said donor roll, so as to form a toner powder cloud in the development zone with detached toner from the toner cloud developing the latent image.
