Cleaning edge modification for improved cleaning blade life and reliability
摘要:
According to aspects of the embodiments, there is provided an apparatus comprising a cleaning unit with a blade holder that rotates about a pivot point, the cleaning blade is coupled to the blade holder and is positioned to chisel excess toner from a photoreceptor surface. Geometrical changes produce a blade having a plurality of slanted surfaces at the working end of the blade one at an obtuse angle, in the range of 93 degrees to 97 degrees, and a second at an acute angle that forms an offset point between the cleaning edge and the intersection of the two angles. A double cut allows for improvement in the cleaning tip stiffness using the first cut, while the second cut increases the contact width and improves the pressure distribution at the working edge.
