DEVELOPMENT ROLLER, METHOD FOR MANUFACTURING THEREOF, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE

摘要

A method for obtaining a development roller capable of giving a high-definition electrophotographic image in various environments.  The method for manufacturing the development roller comprising a shaft core and a resin layer on the periphery of the shaft core and comprising a surface layer on the periphery of the resin layer comprises a process of forming the surface layer by hardening a mixture of carbon black, a specific diol, and a specific isocyanate compound.
