Claims19
A roller comprising:
- an elongated ceramic body having a first end and a second end;
- an aluminum member attached to each of said first end and said second end of said elongated ceramic body;
- and
- two elongated shafts, wherein a shaft is attached to and extending from each of said aluminum members;
- wherein the two elongated shafts are made of a different material than the aluminum members.
A development roller for use in a machine in which marking particles are advanced toward a latent image to form a developed image, said development roller comprising:
- an elongated ceramic body having two ends;
- a member frictionally welded to each of said ends of said elongated ceramic body;
- and
- a shaft attached to each of said members;
- wherein the shafts are made of a different material than the members.
A development unit for use in a printing machine in which marking particles are advanced toward a latent image to form a developed image, said development unit comprising:
- a housing defining a chamber therein for storing a supply of marking particles therein, said housing defining an aperture therein;
- and
- a development roller rotatably mounted to said housing and positioned adjacent the aperture, said development roller adapted to advance said marking particles from the chamber toward the latent image, said development roller including an elongated ceramic body having two ends, a member frictionally welded to each end of said elongated ceramic body, and a shaft attached to each of said members wherein the shafts are made of a different material than the members.
An electrophotographic printing machine of the type in which marking particles are advanced toward a latent image to form a developed image, said printing machine including a development unit, said development unit comprising:
- a housing defining a chamber therein for storing a supply of marking particles therein, said housing defining an aperture therein;
- and
- a development roller rotatably mounted to said housing and positioned adjacent the aperture, said development roller adapted to advance said marking particles from the chamber toward the latent image, said development roller including an elongated ceramic body having two ends, a member frictionally welded to each end of said elongated ceramic body, and a shaft attached to each of said members wherein the shafts are made of a different material than the members.
