DEVELOPING ROLLER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18499244 titled 'DEVELOPING ROLLER

The abstract describes a patent application for a developing roller that includes an electro-conductive shaft core with an elastic layer on its outer surface. The elastic layer consists of a rubber base layer and an incomplete film of resin with a high melting point on top, providing a surface hardness of 37.5 or more in MD-1 hardness.

  • Electro-conductive shaft core with elastic layer
  • Rubber base layer and resin film with high melting point
  • Surface hardness of 37.5 or more in MD-1 hardness

Potential Applications: - Printing industry - Photocopiers - Fax machines

Problems Solved: - Improved durability of developing rollers - Enhanced printing quality

Benefits: - Longer lifespan of developing rollers - Consistent and high-quality prints

Commercial Applications: - Manufacturing of printing equipment - Supplying replacement parts for photocopiers and fax machines

Questions about Developing Roller: 1. How does the resin film with a high melting point contribute to the durability of the developing roller? 2. What are the specific advantages of having a surface hardness of 37.5 or more in MD-1 hardness for the printing industry?

Frequently Updated Research: - Ongoing studies on the impact of different resin compositions on the performance of developing rollers.


Original Abstract Submitted

A developing roller includes an electro-conductive shaft core and an elastic layer provided on an outer peripheral surface of the electro-conductive shaft core. The elastic layer includes a base layer formed of a rubber composition and an outermost layer formed on a surface of the base layer. The outermost layer is an incomplete film formed of a resin with a melting point of 120° C. or higher. A surface hardness of the elastic layer is 37.5 or more in MD-1 hardness.
