Disclosed is a process for affecting a reduction in fusing energy and permitting minimal image de-enhancement which comprises (1) providing a toner composition with toner resin particles, and pigment particles; (2) affecting spheroidization of the aforementioned toner composition; (3) incorporating the spheroidized toner composition into a xerographic imaging apparatus with a flash fusing device incorporated therein; (4) generating an electrostatic latent image in the imaging apparatus; (5) developing the image formed with the spherical toner composition; (6) transferring the image to a supporting substrate; and (7) permanently affixing the image thereto with energy emitted from a flash fusing device.

A yellow toner including:a resin, anda colorant comprising a mixture of a yellow pigment and a yellow dye, wherein the combined weight of the colorant is from about 1 to about 50 weight percent of the total weight of the toner, and wherein the chroma of developed toner is from about 90 to about 130 CIELAB units.

An intermediate transfer member defines a transfer nip with a transfuse member. A cooling platen contacts the intermediate transfer member in the post-transfer nip region. The cooling platen absorbs heat from the intermediate transfer member to evaporate a liquid into a gas. The gas is directed to a heating platen contacting the pre-nip region of the intermediate transfer member. The heating platen condenses the gas to a liquid to heat the intermediate transfer member.

Fabricating belts by forcing adhesive into a belt seam using centrifugal forces. A belt having ends that are fabricated to mate along a seam is inserted into a cylinder such that a seam is formed. An adhesive is then deposited along the seam and the cylinder is spun at a speed sufficient to force the adhesive into the seam. The adhesive is then cured so as to produce a seamed belt.

A cleaning station for a fusing member has first and second cleaner rollers. The first cleaner roller is coated with a sticky or adhesive first toner layer. The first toner layer contacts the fuser member for cleaning. The second cleaner roller is coated with a sticky or adhesive second toner layer. The second toner layer is in contact with the first toner layer. The second cleaner roller defines apertures connecting to an internal reservoir. Excess toner from the second toner layer collects in the internal reservoir.

A reliable non-sliding transfusing assembly is provided for receiving liquid toner images from an image bearing member. The transfusing assembly includes a continuous intermediate transfer belt forming a belt loop and having an inner surface and a toner image carrying outer surface; a first backing roller having a first diameter and mounted into contact with the inner surface of the belt loop for forming a toner image receiving nip between the belt loop and an image bearing member; and a second backing roller mounted oppositely from the first backing roller and into contact with the inner surface of the belt loop for forming a transfusing nip between the belt loop and an external roller. Importantly, the second backing roller consists of a large drive drum for the belt, and has a second diameter many times greater than the first diameter of the first backing roller so as to produce high quality transfused toner images by preventing belt sliding and slippage, as well as image smearing that would other wise result from a relatively small diameter drive roll.

A seamless intermediate transfer member has a reinforcing member in an endless configuration, a filler material such as a polymer and electrical property regulating material to regulate the electrical properties such as surface and bulk resistivity, dielectric constant and charge dissipation. The seamless intermediate transfer member also has good mechanical properties. The reinforcing member can be prepared by any suitable method such as by weaving. Filler material and electrical regulating material can be applied on, around or embedded into the reinforcing member. The member can be employed in an electrostatographic imaging system with more than one toner imaging station. The member can pick up a separate image from each individual imaging station and transfer the combined image to a suitable substrate. The seamless intermediate transfer member is capable of dissipating charge between toner imaging stations, achieving good transfer efficiencies and has a non-stretch characteristic to attain good registration of a toner image.

Provided herein is a system for using a cleaning web in an electrostatic printing process to provide a uniform and thin wax layer on the fuser roll and thereby minimize print history effects, reduce triboelectric voltages on the fuser roll and provide uniform and improved release of the toner from the fuser roll. The application of this beneficial thin film to the fuser roll is accomplished by impregnating the cleaning web with a wax material that is substantially the same as the wax material in the toner used in the system. This impregnated wax, therefore, has the same release and triboelectric properties as the wax in the toner and therefore will not attract residual toner but will rather repel it.

A three-layer transfer member having a rigid substrate, a conformable intermediate layer and an outer thin fluoropolymer layer wherein the fluoropolymer layer can be tetrafluoroethylene, perfluoroalkoxy, fluorine ethylene propene monomers, polymers thereof, and mixtures thereof, and an image apparatus including the same.
摘要:
A printing apparatus employs rheological assist to transfer toner images from an intermediate transfer member to a transfuse member prior to final transfer and fusion of the toner image to a substrate. The transfuse member and intermediate member are maintained at a preestablished temperature differential, the intermediate transfer member being heated above ambient temperature. The preestablished temperature differential rheologically assists the transfer of the toner image to provide complete transfer of the toner image.
