DEVELOPING MEMBER PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

According to the present invention, the deformation recovery properties and superior high temperature, is also provided with a developing member of a high quality satisfying the pilreu within mingseong at low temperatures. A developing member, the mandrel of the present invention, the elastic layer formed on the outer peripheral surface of the mandrel, and includes a surface layer which covers the outer peripheral surface of the elastic layer, the surface layer contains a first resin and second resin, the first resin has a specific structure in a urethane bond between the two adjacent, it said second resin having a specific structure is a glass transition temperature Tg of less than or equal to 120 over 20 resin. ;
