An image forming equipment, e.g., a laser printer includes a photoconductive (PC) drum and an associated charge roller and incorporates a conductive polymer cleaner blade having an electrical potential to sufficiently charge contamination particles on the PC drum to electrically repel from a charged surface, such as the charge roller.

Apparatus and method of reducing charge roller contamination

A roller capable for use as a developer roller in a printer including a roll body having a surface, wherein the roller provides a first surface flexibility (SF) when the roller rotates in one direction and a second surface flexibility (SF) when said roller rotates in a second direction.

Roller with mechanical properties influenced by rotation

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.

Cleaning member for charging device

A developer roller () is rotated rapidly for high speed printing, which can cause excessive heating at end seal (). Heat damage to toner () is avoided by providing gaps () under the seals () which reduce the stiffness of developer roller () and thereby reduce frictional heating.
