ABSTRACT:
Disclosed is an image forming apparatus, in which toner electrically charged in a prescribed polarity is fed from a toner feed device into a toner passage of a toner control device. A predetermined voltage is applied to an electrode of the toner control device in accordance with image signals given by an image information generating device, thereby forming an electric field for directing the toner through the toner passage from the toner-feed side to the toner ejection side of the toner control device. After passing through the toner passage, the toner falls down onto the recording paper placed on a base electrode, thereby forming a desired toner image thereon. Ultrasonic vibration with a variable frequency is applied to the toner control device to allow the toner to uniformly fall down therefrom. A prescribed voltage is applied to the base electrode to form an electric field for accelerating the falling of the toner from the toner control device toward the recording sheet.
