摘要：
A charge roller rotatable in contact with a photoconductive element in the form of a drum or a belt and applied with a voltage for charging the element, and an image forming apparatus using the same. The surface of the charge roller is ground in order to remove toner particles and other impurities firmly deposited thereon, as needed. The charge roller is capable of uniformly charging the photoconductive element at all times.
