Abstract
PURPOSE:To perform satisfactory image formation without generating an image memory by using a two component developer consisting of coloring powder and magnetic powder as the developer housed in a device and specifying the dynamic resistance value of the magnetic powder. CONSTITUTION:The two component developer consisting of a toner and a carrier is used as the developer, and a material whose dynamic resistance value represents a value in a range of 10<7>-10<9>OMEGA.cm is used as the carrier. Namely, the toner with reverse polarity generated due to the injection of electric charge of the toner itself is not generated when the carrier with the value less than 10<7>OMEGA.cm is used, and also, the attachment of the carrier due to the injection of the electric charge of the carrier itself generated in the carrier with the value <=10<7>OMEGA.cm is not generated, and furthermore, it is possible to prevent the effect of the carrier as a confronting electrode from being missed due to the lowering of the execution bias of a developing device by a high resistance carrier >=10<9>OMEGA.cm, and to prevent a cleaning effect and image density from being lowered. In such a way, the image memory and a ghost image, etc., can be prevented from being generated.
