Abstract

PURPOSE:To prevent a clogging of ink jet nozzle due to some floating charged toners etc. by arranging a charged shield member near an ink jet nozzle. CONSTITUTION:An electricity is charged to the shield member 23 to reflect a minus polarity of toners floating in a copying machine. Even if some toners charged to (+) are mixed in the floating toners, they are suctioned into the shield member 23, so that no clogging may be occured in the nozzle 22 of the ink jet head by the floating toners.
