Abstract

PURPOSE:To further effectively prevent the recording paper from coming off from a carrier means by a method wherein in an electrification deflection-type ink jet recording device, the electric field change at the part of carrier means corresponding to the recording paper tip is enlarged. CONSTITUTION:The electrification of ink jet particles and the back polarity electrification are periodically given to the dielectric drum 8, which carries recording paper to be coated with ink jet particles through the charger comprising of a DC source 12, a charge control circuit 13, an aperture board 14 to form a good quality picture. In said device, the pitch (a) of the dielectric 8b of the drum 8, which is the part corresponding to the tip of the recording paper 7, is made so as to be smaller than the pitch (b) of the other parts to enlarge the suction power between the recording paper tip and the drum 8 to prevent the recording paper from coming off the drum thus to improve the type quality.
