ABSTRACT:
A powdered chemical mixture for lubricating photoreceptors, wiper blades, doctor blades and slide seals used on dry toner printers, copiers, and facsimile machines. The dry powder comprises a mica group mineral wet-ground to attain cold, dry lubricity, resiliency and particle alignment. The wet-ground mica-group mineral may be coated by calcium stearate to increase lubricity and reduce static electricity from the photoreceptor and blades during operation of the machine. The optimum powder would be comprised of 99% by weight mica-group mineral and 1% by weight calcium stearate. Muscovite and phlogopite are mica-group minerals suggested for use in the lubricating powder. The calcium stearate could also be used with powdered lubricants other than mica to reduce static electricity during operation of the machines.
