Charging member, charging device including the charging member, process cartridge including the charging device and image forming apparatus including the process cartridge

A process cartridge, comprising:

• a charging device including a charging member comprising:
• an electrically conductive support body;
• an electrical resistance adjustment layer disposed on the electrically conductive support body;
• and
• a surface layer disposed on the electrical resistance adjustment layer,
• wherein the surface layer contains at least polyol resin grafted with fluorine or silicon, polyether polyol resin, and organic anion salt containing fluorine as well as alkali metal or alkali earth metal, and polyisocyanate,
• the charging device and an image support body are supported integrally, and
• the process cartridge is fixed to a main body of an image forming apparatus to be freely detachable.

An image forming apparatus, comprising:

• an image support body;
• a process cartridge including a charging device, the charging device and the image support body being supported integrally, and the charging device including a charging member comprising:
• an electrically conductive support body;
• an electrical resistance adjustment layer disposed on the electrically conductive support body;
• and
• a surface layer disposed on the electrical resistance adjustment layer;
• an exposure device that performs exposure on a surface of the image support body to form an electrostatic latent image;
• an image development device that supplies toner to the electrostatic latent image on the surface of the image support body to visualize the electrostatic latent image;
• a transfer device that transfers onto a transfer media the visualized image on the surface of the image support body, wherein
• the surface layer contains at least polyol resin grafted with fluorine or silicon, polyether polyol resin, and organic anion salt containing fluorine as well as alkali metal or alkali earth metal, and polyisocyanate.
