Abstract
The present invention relates to printing devices and particularly to devices and a method for the reduction of contamination on a charging device. A cleaning member is supplied that has a cleaning material affixed to a substrate. The cleaning material is positioned to contact the charge roller and the substrate is flexed to provide an elastic response.
Claims20
A cleaning device for removing particulate from a charging device in an electrophotographic device comprising:
- an elongated substrate including a pad comprising open-cell foam capable of absorbing particulate;
- said substrate capable of being flexed having first and second portions, wherein said substrate is capable of being positioned between said charging device and a surface in said electrophotographic device;
- wherein said first and second portions define an angle of less than 180 degrees, and wherein said substrate, as positioned between said charging device and said surface 10 in said printer applies a pressure onto said pad when said pad contacts said charging device.
An electrophotographic printing device comprising:
- a photoconductor;
- a charging device contacting said photoconductor;
- an elongated substrate including a pad comprising open-cell foam capable of absorbing particulate;
- said substrate capable of being flexed having first and second portions, wherein said substrate is capable of being positioned between said charging device and a surface in said electrophotographic device, wherein said first and second portions define an angle of less than 180 degrees, and wherein said substrate, as positioned between said charging device and said surface in said printer, applies a pressure onto said pad, when said pad contacts said charging device.
