摘要： Operation of a developer so as to achieve reduced scavenging and reduced direct contamination when using a hybrid developer. A hybrid developer is operated in three modes. The first mode is normal operation in which the developer operates as in the prior art. The second mode is an unloaded standby mode wherein toner is not on the developer's donor roll and wherein the developer's bias potentials are selected to reduce scavenging. The third mode is a loaded standby mode wherein toner is on the developer's donor roll and wherein the developer's bias potentials are selected to reduce direct contamination.

摘要： An electrophotographic reproduction machine including an image bearing member, latent image devices for forming on the image bearing member electrostatic latent images having a first relative polarity, and a hybrid development unit for applying to the latent images correct-sign toner particles having a second polarity relatively opposite to the first polarity. A detecting apparatus adjacent the image bearing member for sensing toner particles developed into non-image regions. The development unit includes a first biasing means including a DC power supply for biasing a magnetic roll mounted within the housing of the hybrid development unit. A second biasing means includes a second DC power for biasing a donor roll mounted which forms a toner transfer nip with the magnetic roll. The DC power supplies is adjusted so that "wrong sign" toner of said first polarity are attracted to the donor roll from the magnetic brush within the housing of the hybrid development unit. An electrostatic field is produced between the image bearing member and the donor roll having a wrong-sign toner thereon. The wrong sign toner is attracted to the image bearing member; and a sensor senses wrong-sign toner on said image bearing member.

摘要： The present invention is an apparatus that develops a latent image recorded on a surface with toner. An electrically biased electrode member in the development zone between the photoconductive member and the donor roll detaches toners from the donor roll so as to form a toner powder cloud in the development zone. The electrical bias applied on the donor member is an asymmetrical wave. Toner from the toner powder cloud develops the latent image.

摘要： A color printing machine with a plurality of toner dispensers has a fewer number of toner dispenser members and control mechanisms than toner dispensers. This is accomplished by locating the toner dispensers in close proximity to one another so that a single toner dispenser member can extend between the plurality of toner dispensers. Various toner dispenser members such as a toner moving member, a toner mixing member and a gating member can be used alone or in combination to aid in dispensing the toner from the toner dispenser. When the toner dispenser member extends through the walls of the toner dispensers, seals must be formed between the toner dispenser member and the toner dispenser walls in order to contain the toner therein.

摘要： In a multi-color imaging apparatus utilizing a recharge step between two image creation steps for recharging a charge retentive surface to a predetermined potential pursuant to forming the second of the two images, a first corona generating device recharges the charge retentive surface to a higher absolute potential than a predetermined potential, and then a second corona generating device recharges the charge retentive surface to the predetermined potential. An electrical charge associated with the first image is substantially neutralized after being recharged by the first and second corona generating device.
