PURPOSE:To prevent the decrease in image density and to eliminate offsetting by incorporating conductive powder and >=2 kinds of low mol. wt. wax into a titled developer thereby eliminating the increase in electrification quantity occuring in friction. CONSTITUTION:An electrifier 8 for electrification, an optical system 9, a two- color developing device 10, an electrifier 11 for transfer, an electrifier 12 for stripping, a cleaner 13 and a destaticizing lamp 14 are successively disposed around a photosensitive drum 7. The electrostatic latent image formed on the drum 7 is developed by using the developer consisting of a toner and carrier in the device 10 and is thus visualized to a toner image. The developer used in this stage contains the conductive powder and >=2 kinds of a low mol. wt. wax. |
