Abstract
A charging roller includes a conductive support, and a roller body to rotate about the conductive support. The roller body includes a conductive elastic layer to contact the conductive support, and a conductive resin layer located around the conductive elastic layer to form a surface of the roller body. The surface has ten-point average roughness Rzjis of approximately 20 μm to 30 μm. The conductive resin layer contains polyrotaxane.
