Abstract:
An image forming apparatus, comprising:a carrier for carrying developer particles; a counter electrode positioned so as to face said carrier; a control electrode section having a plurality of passage pores constituting a passage of developer particles flying from said carrier to said counter electrode, and a plurality of gate electrodes formed one to one around the plurality of passage pores; and potential applying means for applying a potential that is in accordance with an image signal to the plurality of gate electrodes, wherein, in a case where a duration of a transient current generated when a flying preventing potential is applied to each of the plurality of gate electrodes is longer than a duration of a transient current generated when a flying potential is applied to each of the plurality of gate electrodes, said potential applying means applies the flying potential to each of the plurality of gate electrodes while adjusting an apply time of the flying potential so that durations of the transient current generated when the flying preventing potential is applied do not overlap one another.
