    摘要： An apparatus includes an image bearing member for carrying an image; an intermediary transfer member for receiving the image; a primary transfer member for transfer of the image onto the intermediary transfer member in a primary transfer station; a secondary transfer member for transfer of the image onto a transfer material in a secondary transfer station; a first charging member for charging toner remaining in a region upstream of the primary transfer station and downstream of the secondary transfer station; and a second charging member for charging the toner remaining in a region upstream of the primary transfer station and downstream of the first charging member. The first charging member rubs a surface of, and the second charging member moves in contact with, the intermediary transfer member, to transfer the toner remaining on the intermediary transfer member to the image bearing member simultaneously with the primary transfer.

    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.
