Abstract
In a conductive roller having a conductive substrate, a conductive elastic layer and a conductive cover layer, the conductive cover layer is formed of a seamless tube containing a thermoplastic polymer, the surface of the conductive roller is coated with an inorganic compound the particle surfaces of which have been subjected to hydrophobic treatment, and the roller having been coated therewith has a glossiness of from 7.5% or more to less than 22.0%. This conductive roller can make toner and external additives less adhere to the roller surface, can prevent the faulty images due to the adhesion of photosensitive-member abrasion dust and can well perform charging in the image reproduction from the initial stage to the last.
