Abstract:
An apparatus for raising developer from a sump to an elevated position over an electrostatic plate bearing a latent image and cascading the developer over the plate to develop the image including a rotating frame having scoops fastened thereto which are filled with developer as they pass through the sump and empty the developer onto a guide member located at the elevated position which directs the developer over the plate. The scoops are independently mounted for rotation on the frame so that each can be orientated to its optimum position for emptying developer therein when at the elevated position.
Abstract:
An apparatus for improving the developability of a magnetic brush developing system by providing an electrically neutral entrance and exit flow region through which developer material passes as it enters and leaves the development zone. A second mode of operation is also provided for enhancing the system''s ability to develop input images of relatively low density.
Abstract:
Apparatus for separating residual toner particles from a moving photoconductive surface and automatically storing the separated particles within a storage area. A blade element is arranged to move between the photoconductive surface and the residual toner material to separate the toner from the surface and direct the toner into contact with a transport roll. The transport roll moves the toner away from the cleaning zone and into a collecting zone wherein a paddle is rotatably supported to pump the toner into a substantially horizontally aligned storage area. Further means are provided to clean the paddle as it passes through the storage area and to seal the storage area to prevent the separated residual toner from migrating back into the cleaning zone.
