摘要： To prevent image defects such as fog and irregularities caused by the accumulation of the oppositely charged toner by flying the toner toward a photoreceptor to compulsorily consume the toner even though the toner is oppositely charged toner having a small charged amount. A potential difference between the photoreceptor and the development roller is set at a value at which the normally charged toner on the development roller can be flown toward the photoreceptor in the development phase at the time of compulsorily consuming the toner, and this potential difference is set at a value at which the flown normally charged toner can be returned to the development roller in the recovery phase. A development duty and a frequency f are set in such a way that a time period in the development phase is larger than a time taken for the normally charged toner on the development roller to fly to a point located midway between the development roller and the photoreceptor and is smaller than a time taken for arriving at the photoreceptor, and a time period in the recovery phase is larger than a time taken before the normally charged toner arrived at the point located midway between the development roller and the photoreceptor arrives at the photoreceptor, returns to the development roller to beaten out the oppositely charged toner and the oppositely charged toner beaten out flies to the photoreceptor.

摘要翻译： 为了防止由于相反充电的调色剂的积聚引起的图像缺陷，例如通过将调色剂朝向感光体飞行而强制消耗调色剂，即使调色剂具有相反电荷的带电量小的调色剂。 感光体和显影辊之间的电位差被设定为在强制消耗调色剂时显影辊上的正常带电的调色剂能够在显影阶段中朝向感光体流动的值，并且设定该电位差 在正常充电的调色剂可以在恢复阶段返回到显影辊的值。 显影负荷和频率f被设定为使得显影阶段的时间段大于显影辊上的正常充电的调色剂飞行到位于显影辊和感光体之间的位置的时间 并且小于到达感光体所需的时间，并且恢复阶段的时间段大于在正常充电的调色剂到达位于显影辊和感光体之间的位置到达感光体的时间， 返回到显影辊，以殴打带相反电荷的调色剂，并将带相反电荷的调色剂扑灭到感光体中。

摘要： A fixing device for thermally fixing an unfixed image onto a recording sheet by causing the sheet to pass through a fixing nip. The fixing device includes: heat belt formed in an endless shape and provided with a resistance heat layer; first pressure member provided inside a running path of the heat belt; and second pressure member pressing the first pressure member from over the running path to form the fixing nip. At least one of the first and second pressure members is rotating body. The heat belt has a pressure-receiving area and two non-pressure areas. The pressure-receiving area receives pressures from both the first and second pressure members. The non-pressure areas have been arranged at outside of the pressure-receiving area in an axis direction of the rotating body. Two ring-like electrodes have been formed on circumferential surfaces of the non-pressure areas and are used to supply power to the resistance heat layer.
