摘要： A transfer device and an image forming apparatus capable of forming an image of smooth image quality with little uneven density, are provided. An alternating voltage is applied so that a first period in which a first peak-to-peak voltage Vpp(1) is applied and a second period in which a second peak-to-peak voltage Vpp(2), lower than the first peak-to-peak voltage, is applied are alternately repeated. In the alternating voltage to be applied, a transfer side potential to shift a toner from an intermediate transfer belt to recording paper sheet and an opposite transfer side potential to shift the toner from the recording paper sheet to the intermediate transfer belt are applied so as to alternate with each other. When f1 denotes a frequency of the first period and f2 denotes a frequency of the second period, f1=f2 is satisfied.

摘要： A developing unit comprises a magnet roller, a stirring roller, a carrying screw, a toner density sensor, and a sensor level adjusting device. When feeding or exhausting the developing powder, the rollers and screw are driven at a slower or faster rotary speed than the speed given when developing an image. After the supply of the developing powder is terminated, the rotary speed of the rollers and the screw is changed to the speed given for developing an image. After a certain time is elapsed, the adjusting device serves to start the level adjustment when the sensor produces a stable output.

摘要： An image forming apparatus provides a mechanism for exhausting waste toner or developing powder and is constructed to have a sensor for sensing an amount of waste toner in a recovery vessel when the developing powder is sensed to be degraded and a determining unit for determining if the carried developing powder is overflown from the recovery vessel based on the sensed result. If it is determined that it is not overflown, the developing powder is recovered in the recovery vessel. Further, the unit for continuing the formation of an image is also provided. If the recovery vessel may provide a spared space for the waste toner after the developing powder is recovered in the recovery vessel, the formation of the image is continued.
