摘要:
This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.

A process for producing a charging member by grit blasting a charging member substrate, plasma spraying a single component outer coating consisting essentially of titanium dioxide powder directly to the grit blasted stainless steel substrate, and the outer coating has a resistivity of from about 10−10 to about 10−3 ohms-cm.

An apparatus comprises a frame having a first frame section connected to a second frame section. The frame also has at least one physical connection that allows the first frame section to move relative to the second frame section. A first roller is connected to the first frame section. The first roller has a crowned outer surface surrounding an axle. Also, first connectors connect the first roller to the first frame section. The first connectors allow the first roller to rotate around the axle and allow the first roller to move in a direction parallel to the axle. A second roller is also connected to the second frame section. At least one biasing member is connected to the first frame section and the second frame section. The biasing member applies a bias to cause the first frame section to move away from the second frame section. A belt substrate contacts the first roller and the second roller. A latch is connected to the first frame section and the second frame section. The latch allows the frame to collapse by moving the first frame section toward the second frame section and disconnecting the biasing member.

A roller includes a core and a ceramic coating formed over the core. The roller has a composite runout of less than 20 &mgr;m and a total indicator reading runout of less than 7 &mgr;m. The ceramic coating has a smooth finish and has controlled electric properties. This roller can be used as a donor roller for transporting toner to a photoconductive member so as to achieve high-quality image development.

摘要:
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.
