Abstract
In some examples, a printing liquid developer includes a developer roller that has a hollow tubular base body formed of a material including conductive carbon fiber, a conductive, compliant layer around an outer surface of the hollow tubular base body, and an electrically conductive support separate from the hollow tubular base body and electrically contacted to a surface of the hollow tubular base body.
Claims15
A printing liquid developer for a printing system, comprising:
- a developer roller comprising:
- a hollow tubular base body formed of a material comprising conductive carbon fiber;
- a conductive, compliant layer around an outer surface of the hollow tubular base body;
- and
- an electrically conductive support separate from the hollow tubular base body and electrically contacted to a surface of the hollow tubular base body.
2 more elements
A printing system comprising:
- a photoconductive member;
- and
- a printing liquid developer to transfer a printing liquid to the photoconductive member, the printing liquid developer comprising:
- a tubular base body formed of a material comprising conductive carbon fiber, the tubular base body comprising an inner bore;
- a conductive, compliant layer around an outer surface of the tubular base body;
- and
- an electrically conductive support separate from the tubular base body and electrically contacted to an inner surface of the tubular base body, the inner surface defining the inner bore.
4 more elements
A method of forming a printing liquid developer, comprising:
- arranging a conductive, compliant layer around an outer surface of a hollow tubular base body formed of a material comprising carbon fiber;
- and
- attaching a portion of an electrically conductive support to the hollow tubular base body to make electrical contact between the portion of the electrically conductive support and an inner surface of the hollow tubular base body, the inner surface of the hollow tubular base body defining an inner bore of the hollow tubular base body, and the electrically conductive support being separate from the hollow tubular base body.
