A roll cover particularly suitable for a fuser roll has an intermediate layer on the roll body and an outer surface layer including heat transfer bodies therein. The intermediate layer is a graphite sheet having legs extending along the axial extent of the roll body. The outer layer has graphite fibers embedded therein, the graphite fibers extending axially with respect to the roll.

A grounding brush for mitigating static electric charge on a motor shaft includes a plurality of filaments secured to an annular frame around the shaft, with tips of the filaments disposed in a channel defined by the frame. Conductive powder can be provided in the channel to improve current flow from the shaft to the filaments.

A static charge neutralizer for a moving component of an apparatus includes a plurality of filaments on a conductive strip, with tips of the filaments disposed adjacent but spaced from the moving component. The filaments induce ionization in the presence of an electrical field from the statically charged surface of the moving component.

Static charge neutralizing assembly for use on rollers and shafts

A device places a charge on an object passing by and proximate to the device in a first direction along a transport axis. The device includes a body having a surface. A power input is disposed in the body. A plurality of resistors each have a longitudinal resistor axis and each are capable of receiving power from the power input. Each of the plurality of resistors is disposed in the body with the longitudinal resistor axis being generally parallel to the surface. An ionizing pin is electrically connected to each of the plurality of resistors for receiving power to generate ions. The object is charged by passing the object by and proximate to the surface of the body in the first direction to receive ions generated by the plurality of ionizing pins. The device provides a relatively long object dwell time, thereby increasing the amount of time that the area of the object is exposed to an ion stream from the device. The device also has a low profile, heightwise, and thus may be easily retrofitted into conventional conveyors.
