Abstract
A lubricant supplying device including a molded lubricant having a Martens hardness of approximately 40 N/mm2 to approximately 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 approximately 5 deniers to approximately 15 deniers in a circumference of a rotative supporting axis of the rotative member with a density of approximately 20,000 fibers to approximately 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 remove the lubricant shavings remaining on the surface of the image bearing member, and a pressing member configured to press contact the molded lubricant with the rotative member at a pressure force ranging from approximately 2 N/m to approximately 12 N/m.
