    摘要： A first mode to form a toner image of single color where a pressure contact release section T changes a primary transfer section 7 to be in a pressure contact state, and a second mode to form an overlapped toner image where the pressure contact device T changes a plurality of the primary transfer sections 7 to be in the pressure contact state can be executed, wherein a speed difference D1 between an image carrier 1 and an intermediate transfer belt 6 in the first mode is controlled to be greater than a speed difference D2 between the image carrier 1 and the intermediate transfer belt 6 in the second mode.

    摘要翻译： 在第一模式中，形成压力接触释放部分T将一次转印部分7改变为压力接触状态的单色调色剂图像，以及形成重叠调色剂图像的第二模式，其中压力接触装置T改变 可以执行处于压力接触状态的多个一次转印部分7，其中第一模式中图像载体1和中间转印带6之间的速度差D1被控制为大于第一模式下的图像载体1和中间转印带6之间的速度差D2 图像载体1和中间转印带6处于第二模式。

    摘要： An image forming apparatus includes an image carrier for carrying a toner image, a drive device for driving the image carrier at a predetermined speed, a control device for giving instruction to the drive device to perform predetermined operation, and a transfer device for nipping a recording sheet with a rotary member at the position opposed to the image carrier and for transferring the toner image on the image carrier onto the recording sheet, wherein the control device gives instruction to the drive device to generate a variation having a phase which is reverse to a phase of a variation given to the predetermined speed of the image carrier by a vibration produced at the time of passage of the recording sheet between the image carrier and the transfer device.
