The present teachings include a coating composition of a powder of fluorine containing particles, aerogel particles and poly(alkylene carbonate). A method of making a fuser member and the fuser member resulting therefrom is also provided.

Fuser coating composition and method of manufacture

A method of forming and a resulting selectively polished fuser member. The method includes selectively polishing that portion of the fuser member surface not subject to rapid natural wear. The method further includes polishing both a surface region subject to rapid sheet edge wear and a surface region not subject to rapid sheet edge wear, and polishing the surface region not subject to rapid sheet edge wear more than the surface region subject to rapid sheet edge wear. The rapid natural wear corresponds to sheet edge wear on the fuser member surface.

Selective polishing of fuser members

This is a process to restore compression set properties of a silicone rubber fuser structure that has been damaged during the coating of the silicone with Teflon; Teflon is a registered trademark of DuPont. This restoration is achieved by re-baking the coated fuser roll at temperatures of 175&#xb0; C. to 275&#xb0; C. This will improve the compression set and will give the fuser structure improved life and provide better image quality.

Apparatus is provided for superpolishing the inside diameter surface of a seam of a flexible continuous photoreceptor belt. The apparatus includes (a) spaced apart support rollers for supporting the inside surface of the flexible continuous photoreceptor belt into a loop having strands, including a seam strand, between adjacent rollers; (b) a polishing machine mounted adjacent the seam strand, the polishing machine having: (i) polishing forms defining a path for the seam strand; (ii) a rotatable drum for supporting and carrying a polishing media material against the inside surface of the seam on the seam strand, (iii) sets of pinch rolls for clamping the seam strand and straddling the seam thereon; (iv) polishing media material mounted over the rotatable drum and through the path between the polishing forms for contacting the inside surface of the seam; and (v) a reciprocating superpolishing head for reciprocating relative to a width of the flexible continuous belt and a length of the seam, thereby simultaneously (x) reciprocating the superpolishing head in contact with the inside surface of the seam along the length thereof, (y) moving the seam with the sets of pinch rolls, and (z) rotating the drum for move the polishing media material in polishing contact with the inside surface of the seam and across a width of the seam to achieve required random superpolishing motion against the inside surface of the seam.

An imageable belt includes a seam that is finished using an abrasive finishing machine. The seam comprises a seam width with adhesive material disposed thereon. The finishing process includes an abrasive finishing media with a finishing surface and a backer bar. The backer bar comprises a backer bar radius. The backer bar surface is positioned against the belt inner surface so that the belt outer surface contacts the finishing surface to define a finishing contact arc with respect to the backer bar radius. A tension, feed rate and pressure are applied to the finishing media. Using the finishing machine, the seam is then finished to remove the adhesive material. The finishing process results in a seam that is imageable. In one embodiment, the backer bar radius is adjusted so that the finishing contact arc covers the seam width.

A locating feature comprises a plate and a protrusion extending outwardly from the plate. The protrusion includes a substantially linear portion extending from the plate and a dome shaped portion extending from the linear portion.

A development apparatus includes a housing defining a chamber holding a supply of two-component developer material including toner, and magnetizable carrier beads. The development apparatus also includes an increased reliability roller assembly within the housing for repeatably transporting a desired quantity of attracted developer material through a development zone. The roller assembly includes a first and a second preformed end cap sections each having a stub shaft portion and a cylindrical capping portion connected to the stub shaft portion and having an outer surface and assembly recesses formed into the outer surface. The roller assembly also includes a sleeve section connecting the first and the second preformed end cap sections, the sleeve section being spincast as a layer over each of the cylindrical capping portions, and into the assembly recesses of the end cap sections, so as to precisely and reliably assemble each capping portion, to the sleeve section.
