    • An image forming apparatus includes a first toner image bearing member, a second drum, an intermediary transfer member, or belt, a secondary transfer member, a toner charging member, and a controller for controlling an operation in a single-color image forming mode and an operation in a multi-color image forming mode. The controller effects, in a post-processing operation after the operation in the single-color image forming mode in which the toner image is formed on the first drum is ended, control such that a separation state between the drum and belt is switched to a contact state between the image bearing member and belt and then the toner deposited on the toner charging member is collected onto the second drum via the belt and then is collected by a cleaning device provided for the second drum.

    • In an image forming apparatus adapted to form images by employing a plurality of image bearing members, when a monocolor mode is selected, no toner image is formed on photosensitive drums of the colors other than the photosensitive drum on which a black toner image is formed. However, the photosensitive drums of the remaining colors continue to run while maintaining a speed difference in a four-full-color mode in relation to an intermediary transfer belt. As a result, some photosensitive drums reach their service life even if the toners contained in developing devices have not yet run out or even if images have not yet been formed on a predetermined number of transfer materials. To solve the problem, the peripheral speed of each of the photosensitive drums in the black monocolor mode for producing monochrome images is set to be faster than that in the full-color mode so as to make the peripheral speed virtually equal to the moving speed of the intermediary transfer belt.
    • 在适于通过使用多个图像承载部件形成图像的图像形成装置中,当选择单色模式时,在形成黑色调色剂图像的感光鼓之外的感光鼓的感光鼓上不形成调色剂图像。 然而,与中间转印带相比,剩余颜色的感光鼓继续运行,同时以四全色模式保持速度差。 结果,即使容纳在显影装置中的调色剂尚未耗尽或即使图像尚未形成在预定数量的转印材料上,一些感光鼓也能够达到其使用寿命。 为了解决这个问题,用于产生单色图像的黑色单色模式中的每个感光鼓的圆周速度被设置为比全色模式更快,使得圆周速度实际上等于 中间转印带。

    • An image forming apparatus includes a first toner image bearing member (drum); a second drum; an intermediary transfer member (belt); a secondary transfer member; a toner charging member; and a controller for controlling an operation in a single-color image forming mode and an operation in a multi-color image forming mode. The controller effects, in a post-processing operation after the operation in the single-color image forming mode in which the toner image is formed on the first drum is ended, control such that a separation state between the drum and belt is switched to a contact state between the drum and belt and then the toner deposited on the toner charging member is collected onto the second drum via the belt and then is collected by a cleaning device provided for the second drum.
