Abstract (en)
[origin: EP0657786A1] A combination developer and toner delivery roller (12) is used to carry a layer of liquid toner (48) to a development nip (46) formed between the conductive surface of roller (12) and the undeveloped, imaged photoconductor surface (44) so as to reduce preexposure of the undeveloped, imaged photoconductor surface (44) to minimize independent fringe field induced edge effect development. The layer of liquid toner (48) is applied to the surface of roller (12) by either contact with an elongated meniscus of liquid toner emanating from elongated slot (22) in toner delivery assembly (14), or by a spray application through a plurality of toner spray nozzles (54). <IMAGE>
