A reproduction apparatus fuser providing for tuning of the fuser operating parameters to match the gloss of a fused marking particle image to the gloss of a receiver member to which such image is fused. The fuser includes a heated fuser roller, with a pressure roller in adjustable nip relation with the heated fuser roller. A mechanism regulates the speed of transport of a receiver member through the nip between the heated fuser roller and the pressure roller. A control device selectively, individually adjusts the temperature of the heated fuser roller, the pressure in the nip between the heated fuser roller and the pressure roller, and the receiver member transport speed regulating mechanism in an optimum predetermined manner based upon the characteristics of a receiver member upon which a marking particle image is to be fused.

A fuser member having improved toner offset release and wear characteristics. The outermost layer comprises a fluoroelastomer with thermally conductive fillers which are surface treated with a coupling agent that is interactive with the fluoroelastomer and with a release agent which may, optionally, be used on the surface of the fluoroelastomer layer.

A belt fusing accessory, for a reproduction apparatus, the belt fusing accessory providing selectable image gloss. The belt fusing accessory, as disclosed, includes a heated fuser roller and a pressure roller in nip relation with the fuser roller. A steering roller is located downstream of the nip between the fuser roller and the pressure roller. A fusing belt is entrained about the fuser roller and the steering roller. Heat to the fuser roller is controlled dependent upon the desired gloss condition for the colorant image on the receiver member.

Belt fusing accessory with selectable fused image gloss

A toner fuser member having improved toner release properties comprises a substrate and an outermost layer comprising a cured fluoroelastomer that includes at least about 21 mole percent of hexafluoropropylene (HFP) and at least 10 parts per weight of a metal oxide selected from the group consisting of cupric oxide, plumbous oxide, and mixtures thereof. Applying to the outermost layer of the fuser member an effective amount of a polymethyldisiloxane (PDMS) release agent that, optionally, includes at least one functional group reactive with the fluoroelastomer, followed by incubation at an elevated temperature, produces a surface having enhanced toner release characteristics on the outermost layer. A process for forming a toner fuser member having improved toner release properties comprises forming on a substrate an outermost layer having the above-described composition of cured fluoroelastomer and metal oxide.

In an electrostatographic reproduction apparatus capable of producing duplex copies, an intermediate transfer member is utilized for transferring a marking particle image from a member upon which such marking particle image is initially formed to the intermediate transfer member and thereafter from the intermediate transfer member to a receiver member. A fuser assembly, dispensing fuser oil to prevent offset of a marking particle image to the fuser assembly, is then utilized for fixing a transferred image on the receiver member. In order to prevent fuser oil contamination defects on copies produced by such reproduction apparatus, the intermediate transfer member and the member upon which a marking particle image is initially formed are rotated in timed relation to effect registered transfer of such marking particle image from the member to the intermediate transfer member during a print cycle. The starting point for marking particle image formation on the member upon which a marking particle image is initially formed, and thus the starting point for transfer to the intermediate transfer member for successive print cycles is adjusted, whereby the starting point for successive print cycles precesses along the surface of the intermediate transfer member.

Reproduction apparatus image transfer control for preventing fuser oil

A fuser member is provided comprising a support; a fluoroelastomer layer on said support comprising a fluoroelastomer consisting essentially of from 42 to 58 mole percent vinylidene fluoride, 26 to 44 mole percent tetrafluoroethylene, and 5 to 22 mole percent hexafluoropropylene.

A fuser for fixing toner, for example, toner images, includes thermoelectric control devices for controlling temperature. Preferably, the thermoelectric control devices are used to heat the toner in a heating zone and cool the toner in a cooling zone prior to separation of the toner from a fusing surface. The cooling improves both the gloss and the separation characteristics of the toner.

Fuser having thermoelectric temperature control

A toner release agent composition for electrostatography comprises a polydialkoxysilane oil and a concentration of a nonionic surfactant that is effective to prevent or substantially suppress triboelectric charging of pressure and fuser members during fusion of thermoplastic toner on a receiver. The nonionic surfactant preferably comprises about 1 to 10 weight percent, more preferably about 2 to 5 weight percent, of the release agent composition.

Static charge-suppressing release agent compositions

To assist transfer of toner images from a first transfer surface to a second transfer surface, the first transfer surface is actively cooled to prevent the toner sticking to it. Preferably, the cooling is accomplished by thermoelectric control device strips positioned in heat conducting relation with the first transfer surface. A thermoelectric control device can also be used to heat a second or receiving surface to which the toner is to be transferred to farther assist the transfer process.

Method and apparatus for transferring toner

A process and system for inhibiting toner offset in a electrostatographic apparatus of the kind wherein toner images are contact fused to a copy sheet. Drops of offset inhibiting liquid are discretely directed to predetermined locations on the contacting surface of the apparatus fuser member. For example, a drop on demand, piezoelectric drop generator can controllably jet drops of silicone oil to form desired offset inhibiting patterns in accord with apparatus control signals, indicative of particular copy sheet and image requirements.

Electrostatographic apparatus having fusing process and system for

A system for assisting the transfer of a toner image formed by electrostatographic apparatus and process to a copy sheet. The transfer assistance system and process utilize drop generators to form a release liquid pattern for joining with such toner image and a supply mechanism delivers release material, e.g., heat wax material, to the drop generators. In a preferred mode release liquid is applied, in a patterns customized to toner patterns, to an intermediate transfer member.
