    • An image forming apparatus including an image forming device, a transfer device, a fixing device, an inverting device, and a processor. The transfer device includes an intermediate transfer member, a nip forming member, and an electric potential difference generator to generate an electric potential difference between the intermediate transfer member and the nip forming member. The processor causes the electric potential difference generator to generate a first electric potential difference containing only a DC component when a toner image is transferred onto a first side of a recording sheet, and to generate a second electric potential difference containing a DC component and a superimposed AC component when the toner image is transferred onto a second side of the recording sheet. The second electric potential difference has an averaged absolute value per unit of time smaller than an absolute value of the first electric potential difference.
    • 一种图像形成装置,包括图像形成装置,转印装置,定影装置,反转装置和处理器。 转印装置包括中间转印部件,辊隙形成部件和电位差发生器,以产生中间转印部件和辊隙形成部件之间的电位差。 当调色剂图像转印到记录片材的第一面上时,处理器使电位差发生器产生仅包含直流分量的第一电位差,并产生包含直流分量和叠加的第二电位差 当调色剂图像转印到记录纸的第二面上时,AC分量。 第二电位差具有比第一电位差的绝对值小的单位时间的平均绝对值。
