==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:

==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.
