| titleOfInvention | Charging roller, process cartridge, and electrophotographic apparatus |
| abstract | Provided is a charging roller for an electrophotographic apparatus capable of outputting a good image in which a banding image generated after being left in contact with a photoconductor for a long time in an electrophotographic apparatus is suppressed. Accordingly, a charging roller according to the present invention is a charging roller having at least one elastic layer outside a metal support having a cylindrical shape with a radius R, the axis of the support being the center. The area surrounded by a circle having a radius R / 8 is X1 and the area surrounded by a circle having a radius 7 / 16R and a circle having a radius 9 / 16R around the axis of the support is X1. When the Vickers hardness of the support is X2, and the Vickers hardness of the support in an area surrounded by a circle having a radius of 7 / 8R and a radius R centered on the axis of the support is X3, the following relationship is established: Charging rollers satisfying the expressions (1) to (4): 170 ≦ X1 ≦ 235 (1), 210 ≦ X2 ≦ 275 (2), 220 ≦ X3 ≦ 290 (3), X1 <X2 <X3 (4).
