| description | An apparatus for developing a latent image recorded on a surface, including a housing defining a chamber storing a supply of toner. A toner donor member is spaced from the image bearing surface and adapted to transport toner to a region opposed from the surface. A charging device is disposed in the chamber for ion charging the toner. An air injection system fluidizes the toner in the chamber. The injection system and a transport member cooperate with one another to define a region wherein a substantially constant quantity of toner having a substantially constant ion charge is deposited on the transport member. The toner is electrostatically transferred from the transport member to the donor member which contains interdigitated electrodes positioned near the surface of a dielectric core roll. An AC voltage is applied between the interdigitated electrodes to detach toner from the donor member so as to form a toner cloud for developing the latent image in an image on image process. |
