Abstract
Disclosed is a developer roller comprising a first section comprising a first exterior surface, wherein the first exterior surface comprises an electrically-conductive material; and a second section comprising a second exterior surface, wherein the second exterior surface is non-electrically-conductive. The second section is axially aligned with the first section and provided at a first longitudinal end of the first section.
Claims15
A developer roller comprising:
- a first section comprising a first exterior surface, wherein the first exterior surface comprises an electrically-conductive material;
- and
- a second section comprising a second exterior surface, wherein the second exterior surface is non-electrically-conductive,
- wherein the second section is axially aligned with the first section and provided at a first longitudinal end of the first section.
A roller for use in an electrostatic print apparatus, the roller comprising:
- an electrically-conductive section;
- and
- a non-electrically conductive cap at a longitudinal end of the electrically conductive section.
A method of making a developer roller for a print apparatus, the method comprising:
- attaching a non-electrically-conductive cap to an electrically-conductive element, such that the electrically-conductive element and the cap are axially aligned, to form a subassembly;
- and
- providing a non-electrically-conductive coating on an exterior surface of the subassembly, the exterior surface being defined in part by the element and in part by the cap.
