摘要:
A process for cleaning imaging members which comprises applying thereto subsequent to the formation and development of images a composition comprised of resin particles, carbon black particles, magnetite, charge additive, or a mixture of charge additives, and a wax component comprised of polymeric alcohols of the formulaCH.sub.3 (CH.sub.2).sub.n CH.sub.2 OHwherein n is a number of from about 30 to about 300, and thereafter removing said composition.
摘要:
A toner composition comprised of resin, pigment, and a mixture of charge enhancing additives comprised of a first additive of distearyl dimethyl ammonium methyl sulfate, and a second additive comprised of a tetraalkyl ammonium bisulfate.
摘要:
An apparatus and process for reducing accumulation of toner from the surface of an electrode member in a development unit of an electrostatographic printing apparatus by providing an organic coating on at least a portion of the electrode member.
摘要:
A marking particle color blending device for use in an electrophotographic printing machine of the type having an electrostatic latent image recorded on a photoconductive member is provided. The device includes a first container for storing a first supply of marking particles defining a first color and a second container for storing a second supply of marking particles defining a second color. The device further includes a mixing chamber operably associated with the first container and the second container for receiving a least a portion of at least one of the first supply of marking particles and the second supply of marking particles. The device also includes a first metering device operably associated with the first container and the mixing chamber for accurately controlling the quantity of the first supply of marking particles entering the mixing chamber. The device further includes a second metering device operably associated with the second container and the mixing chamber for accurately controlling the quantity of the second supply of marking particles entering the mixing chamber.
摘要:
A process for the preparation of developer compositions comprising providing a first developer comprised of carrier and first toner comprised of resin, pigment, polyolefin, compatibilizer, charge control agent, and surface additive, and adding thereto a second replenisher comprised of carrier, and second toner comprised of resin, pigment, polyolefin, compatibilizer, charge control agent, and surface additive, and wherein the surface additive of the second toner is present in a lesser amount than the surface additive of the first toner.
摘要:
Toner removal device for removing residual toner and debris from a charge retentive surface after transfer of toner images from the surface. This device is characterized by the use of a pair of detoning rolls, one for removing toner from a biased cleaner brush and the other for removing debris such as paper fibers and Kaolin from the brush. The rolls are electrically biased so that one of them attracts toner from the brush while the other one attracts debris. Thus, the toner can be reused without degradation of copy quality while the debris can be discarded.
摘要:
A waste toner reclamation process includes collecting waste toner, screening the collected waste toner, meltmixing the screened waste toner with a second toner, and extruding, grinding and classifying the mixed toner product, wherein the collected waste toner comprises a mixture of different colored toner particles.
