摘要： There is a charge member which charges secondary transfer remaining toner on an intermediate transfer member to a polarity opposite to a normal charge polarity. The transfer remaining toner charged by the charge member is moved in the direction opposite to that of normal toner by a transfer bias and moved 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, waste toner can be collected into the BK station (simultaneously with the transfer). In a full-color mode, since each transfer bias is applied to all stations, the waste toner is collected into the station on the uppermost stream. Thus, the image bearing member for collecting the transfer remaining toner on the intermediate transfer member is made different according to the mode, thereby suppressing that the collection of the waste toner is concentrated on one image bearing member.

摘要： An image forming apparatus comprises an image forming part and a density calibration control part. The image forming part forms an image in any one of a plurality of image forming modes with respectively different processing speeds. The density calibration control part performs image density control for the image forming part in a state where any one of the plurality of image forming modes is applied. Herein, the density calibration control part makes a performing time interval for the image density control in a first image forming mode and a performing time interval for the image density control in a second image forming mode different from each other.
