ELECTROPHOTOGRAPHIC MEMBER AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18584040 titled 'ELECTROPHOTOGRAPHIC MEMBER AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS
The patent application describes an electrophotographic member consisting of a base material, an elastic layer made of silicone rubber, and a surface layer made of fluoro rubber with a thickness of 3 μm or more.
- The elastic deformation power (ηIT) of the surface layer is 30 to 50% as calculated from a load displacement curve obtained through a nanoindentation test.
- The Martens hardness of the outer surface of the surface layer is 12.0 to 18.0 N/mm.
Potential Applications: - This technology can be used in electrophotographic printing processes. - It can also be applied in photocopiers and laser printers.
Problems Solved: - Provides improved durability and wear resistance in electrophotographic systems. - Enhances the quality and longevity of printed materials.
Benefits: - Increased longevity of electrophotographic components. - Improved print quality and consistency. - Reduced maintenance and replacement costs.
Commercial Applications: Title: Enhanced Electrophotographic Members for Improved Printing Performance This technology can be utilized by manufacturers of printers, photocopiers, and other electrophotographic equipment to enhance the quality and durability of their products, leading to higher customer satisfaction and potentially increased market share.
Questions about the technology: 1. How does the combination of silicone rubber in the elastic layer and fluoro rubber in the surface layer improve the performance of the electrophotographic member? - The combination of these materials provides enhanced durability, wear resistance, and print quality in electrophotographic systems.
2. What are the specific advantages of having a Martens hardness of 12.0 to 18.0 N/mm in the outer surface of the surface layer? - A Martens hardness within this range ensures the surface layer can withstand the rigors of printing processes while maintaining flexibility and resilience.
