PURPOSE:To reduce charging and correcting circuits by a method wherein ink drops in other row of particles are rendered into guard drops when the ink drops in rows of particles having a plurality of rows of ink jet particles are being charged and the rows of particles to be charged are switched sequentially. CONSTITUTION:In an ink jet recorder generating a plurality of rows C, M, Y of ink jet particles, when data of cyanogen C are sent to a charging and correcting circuit 10 from a shift 8C after then are selected in a multiplexer 9, a charging code based on the cyanogen data is sent into a D/A transducing circuit 11 and is impressed to a charging electrode of a head for the cyanogen C through an amplifier 13. In the similar manner, a magenta M and an yellow Y data are selected sequentially and particles corresponding thereto are charged, however, ink drops in the rows of particles which are not selected become guard drops. Whereby, the complexed and expensive charging and correcting circuit may be used commonly under a time division. |
