Abstract
A pair of rotary deflection electrodes are provided to confront with each other in an ink jet system printer in order to deflect charged ink droplets emitted from a nozzle as they pass through a high voltage electric field established therebetween. Cleaners are installed close to the rotary deflection electrodes at the position where the electric field established between the rotary deflection electrodes will not be disturbed by the cleaners in order to sweep the rotary deflection electrodes as they rotate.
