PURPOSE:To obtain images which are good in filling of solid images and filling of medium contrast without receiving the influence of a counter charge by using a two-component type developer formed by mixing and agitating a photoconductive carrier consisting of a magnetic material and a photoconductive material-contg. resin and an insulating toner without irradiation with light at the time of frictional electrification and making development simultaneously or right after photoirradiation from a conductive base side. CONSTITUTION:The two-component type developer formed by mixing and agitating the photoconductive carrier consisting of the magnetic material and the photoconductive material-contg. resin and the insulating toner without irradiation with light at the time of the frictional electrification is used and the development is made simultaneously or right after photoirradiation from the conductive base side. The execution of high-efficiency electrostatic charge at the time of the frictional electrification is possible in this case and the attenuation of the carrier counter charge at the time of the development is possible. Thus, the high-quality images which are good in filling of the solid images and filling of the medium contrast are obtd. without receiving the influence of the counter charge. |
