Abstract
A lubricant supplying device including a molded lubricant having a Martens hardness of about 40 N/mm2 to about 70 N/mm2 measured with a test force of 50 mN and a load-applying period of 30 seconds, a rotative member including a fibrous brush of a thickness of about 5 deniers to about 15 deniers in a circumference of a rotative supporting axis of the rotative member with a density of about 20,000 fibers to about 100,000 fibers per square inch, and configured to apply lubricant shavings of the molded lubricant to an image bearing member held in contact with a cleaning member and to remove the lubricant shavings remaining on the surface of the image bearing member, and a pressing member configured to press the molded lubricant against the rotative member at a pressure force ranging from about 2 N/m to about 12 N/m.
