Abstract

An electrostatographic photoreceptor toner cleaning blade composition containing a poromeric, composite material made of non~wovenpolyester fibers bound together with polyurethane. Such materials may be available under the trademark uGeoniteu. Mechanical, electrical, and friction properties of the blade composition can be easily modified by impregnating the porous structure with modifying materials

An electrostatographic photoreceptor toner cleaning blade
composition containing a poromeric, composite material
made of non~wovenpolyester fibers bound together with
polyurethane. Such materials may be available under the
trademark uGeoniteu. Mechanical, electrical, and friction
properties of the blade composition can be easily modified by impregnating the porous structure with modifying
materials

Variations in abrasion resistance, hardness, resilience,
and load bearing capacity can be achieved by impregnation
with various suitable materials. The blade can be impreg~
nated with a conductive material for control of resis~
tivity and/or electrical biasing of the blade edge.
Alternatively, or in addition, low friction or lubricant
materials known for external photoreceptor application can
be used for blade impregnation to achieve a lower coeffi~ cient of friction.

The poromeric composite, modified or not, may be coated
or bonded to other resins or metals for use as composite
blade structures.
