    摘要: An image forming apparatus and an image forming method are characterized in that charged particle jumping can be controlled by applying signals having a small potential difference, and that low-voltage type switching devices can be used as switching devices for the power source. Control electrodes 16 are provided to move charged particles detached from a development roller 2 and to control the movement amount of the charged particles by generating a transfer electric field directly or indirectly between the development roller 2 and a rear electrode 8. A bias electrostatic field is generated between the development roller 2 and the control electrodes 16 by applying a voltage under a jumping start voltage, which is a voltage having the polarity opposite to the polarity of the charged particles and is lower than the jumping start voltage for detaching the charged particles from the development roller 2.
