Patent number: 8092359Abstract: A fuser member for toner fusing systems and processes. This fuser member has a fuser base and a fusing surface layer, and the fusing surface layer contains a fluoroelastomer and filler particles. The filler particles have a mean particle diameter greater than 5 microns, and a modulus greater than the modulus of the fluoroelastomer at fusing temperatures. The fusing surface layer has at least the minimum proportion by volume of these particles, with at least the minimum mean particle diameter, that will provide the fusing surface layer with an equilibrium surface roughness so that, in fusing toner to substrate, the fuser member generates an image having a gloss number less than 10.Type: GrantFiled: October 23, 2003Date of Patent: January 10, 2012Assignee: Eastman Kodak CompanyInventors: Jerry A.

Patent number: 7054572Abstract: The present invention is in the field of electrophotographic printers and copiers. More specifically this invention relates to the fuser apparatus used to fuse an image on a receiving sheet. According to just one aspect of the invention, an apparatus and process for fixing toner images to a receiving sheet is provided. The apparatus may include a fuser having a run condition and an idle condition, the fuser having a fuser roller, a fuser roller heater, and a fuser temperature sensor which inputs to a logic and control system which controls the heating of the fuser roller heater. The fuser roller may be cooled during or after the idle condition, prior to the first receiving sheet entering the fuser. The fuser roller has end portions and a middle portion, and the middle portion may be cooled relative to said end portions. Additional aspects and representative embodiments are described herein.Type: GrantFiled: March 5, 2004Date of Patent: May 30, 2006Assignee: Eastman Kodak CompanyInventors: Susan C. Baruch, Alan R.

Patent number: 5319426Abstract: Image forming apparatus includes a logic and control which receives an input indicative of the compliance of a fusing roller and adjusts the temperature of the fuser in response to that input. The apparatus also can receive an input indicative of the melt viscosity of one or more toners making up an image to be fused to similarly adjust the fusing temperature. Alternatively, the pressure in a fusing nip can be adjusted in response to either or both inputs. The inputs can be received in the logic and control from a fusing roller cartridge having machine readable indicating device, indicative of the compliance of the fusing roller. Similarly, the melt viscosity of the toner can be input from a machine readable indicia or the like on a toner bottle.Type: GrantFiled: December 2, 1992Date of Patent: June 7, 1994Assignee: Eastman Kodak CompanyInventors: Susan C.

Patent number: 5084731Abstract: An electrostatographic fusing apparatus includes a sheet decurling mechanism that has a curl indicating device and a pair of selectable sheet decurling nips formed by a set of hard rollers and a soft roller. The curl indicating device predicts the degree of toner particle laydown of a toned image on an image frame from the value of charge on such frame relative to a given standard charge value of charge. A copy sheet receiving toned images from an image frame having a charge value higher than such standard charge value is selectively deflected through a first decurling nip where the soft roller directly contacts the toned image side of such a copy sheet in order to induce therein a convex curl.Type: GrantFiled: December 24, 1990Date of Patent: January 28, 1992Assignee: Eastman Kodak CompanyInventor: Susan C.
