The residual ink left between the pair of electroconductive members is removed by; and applying a voltage to the residual ink so as to reduce the adhesiveness of the ink disposed on one of the pair of electroconductive members, thereby to remove the ink from the electroconductive member and transfer it to another electroconductive member.
