PURPOSE:To achieve the simplification of the construction of drum by group- dividedly energizing multistyli. CONSTITUTION:A printed substrate 12 formed with a plurality of printed conductors corresponding to the number of contactors in ring-form is held secured to the end plate f2 of a drum 1. These printed conductors are held connected to contactors. These printed conductors are held slide-contacted to each of the contactors on the outside of the drum 1. When recording energizing voltage is applied in time division to each of the lead wires of external contactors during the time of latent image formation by multistyli 4, the electrostatic latent images are formed on the surface of dielectric 2 by the combination of said voltage application and the needle-form electrode time-division energizing of the multistyli 4. |
