    摘要： A charge member charges secondary transfer remaining toner on an intermediate transfer member to a polarity opposite to a normal charge polarity. The remaining toner is moved by a transfer bias, from the intermediate transfer member onto an image bearing member. A BK station is arranged on the downstream of other stations. In a continuous BK monochromatic mode, by applying a reverse bias to transfer portions of the other stations and applying the transfer bias only to the BK station, remaining toner can be collected into the BK station (simultaneously with the transfer). In a full-color mode, remaining toner is collected into the station on the uppermost stream. Thus, the image bearing member for collecting remaining toner on the intermediate transfer member differs according to the mode, thereby suppressing the collection of remaining toner being concentrated on one image bearing member.

    摘要翻译： 充电构件将中间转印构件上的二次转印剩余调色剂充电到与正常电荷极性相反的极性。 剩余的调色剂通过转印偏压从中间转印部件移动到图像承载部件上。 其他车站下游设有BK车站。 在连续的BK单色模式中，通过施加反向偏压来转移其它工位的部分并将转印偏压施加到BK工位，剩余的调色剂可以被收集到BK工位（与转印同时）。 在全色模式下，剩余碳粉被收集到最上游的车站。 因此，根据模式，用于收集中间转印部件上的剩余调色剂的图像承载部件不同，从而抑制剩余调色剂的收集集中在一个图像承载部件上。
