| titleOfInvention | Developing device, process cartridge and electrophotographic image forming apparatus |
| abstract | An object of the present invention is to stably produce high-quality electrophotographic images with little fog even when a developer containing a magnetic material is used to form a large number of electrophotographic images over a long period of time in a high-temperature, high-humidity environment. To provide a developing device that can be formed by A developing device includes a developer and a developing member (developing roller) carrying the developer on its surface, the developing roller comprising a conductive base 2 and a surface layer on the base. 1, the surface layer 1 has a binder resin, the binder resin includes a crosslinked urethane resin and a crosslinked acrylic resin, and is located at a depth of 0 from the outer surface of the surface layer. In the first region up to .1 μm, the crosslinked urethane resin and the crosslinked acrylic resin constitute an interpenetrating polymer network structure, and the developer contains at least a binder resin and a magnetic material. Contains particles. [Selection drawing] Fig. 1 |
