ABSTRACT:
An apparatus for developing an electrostatic image on a photosensitive member or on a record member using one-component developer is provided. The developer comprises a magnetic toner or non-magnetic toner having a volumetric resistivity of not less than 10.sup.6 .OMEGA.cm. The apparatus comprises a developing roller at least the surface portion of which is formed of elastic rubber, means for supplying toner to the surface of the developing roller, and means for charging the toner on the developing roller to a given polarity. The developing roller is driven for rotation at a peripheral speed which is equal to or greater than the speed of movement of the image carrying member. Additionally, the apparatus includes levelling means for levelling the toner on the developing roller, charge neutralizing means for eliminating the electric charge from the toner after the developing step, and scraper means for stirring the toner after the developing step. Various modifications and limitations of the means and members mentioned are possible.
