摘要： An apparatus which develops an electrostatic latent image recorded on a photoconductive member with toner. Fluidized toner is transported from one end of the developer housing to the other end. An electrical bias is applied between the toner mover and the donor roller so as to attract toner to the donor roller. A rotating rod resiliently urged into contact with the donor roller charges and meters the toner on the donor roller. Electrically biased wires in the development zone between the photoconductive member and the donor roller detach toners from the donor roll so as to form a toner powder cloud in the development zone. Detached toner from the toner powder cloud develops the latent image.

摘要： The present invention uses a scavengeless development system in which toner detachment from a donor and the concomitant generation of a controlled powder cloud is obtained by AC electric fields supplied by self-spaced electrode structures positioned within the development nip. The electrode structure is placed in close proximity to the toned donor within the gap between the toned donor and image receiver, self-spacing being effected via the toner on the donor. Such spacing enables the creation of relatively large electrostatic fields without risk of air breakdown.

摘要： An apparatus which develops a latent image recorded on an image receiving member with developer material. A chamber in the developer housing stores a supply of developer material. A donor roll is positioned in the chamber of the housing so as to transport developer material into contact with the latent image to develop the latent image. A rotating, elongated member fluidizes the developer material. As developer material is discharged from a storage container into the chamber of the developer housing, it exerts pressure on the fluidized developer material to move the developer material from one end of the housing to the other end thereof. An electrical bias is applied between the elongated member and the donor roll so that developer material is attracted to the donor roll as the developer material advances from one end of the developer housing to the other end thereof.

摘要： An apparatus for developing a latent image recorded in a surface of a flexible photoconductive member. The apparatus includes a developer unit having a developer roll and a backing member. The roll is positioned opposed from the surface of the flexible photoconductive member and is used for developing the latent image with developer material. The backing member has an arcuate surface in engagement with a surface of the flexible photoconductive member opposed from the surface having the latent image recorded thereon. The flexible photoconductive member is wrapped about at least a portion of the arcuate surface of the backing member to form a negative wrap angle opposed from the developer unit. The centerpoint of the developer roll, the centerpoint of the backing member and the centerpoint of the arcuate surface are colinear.
