    • An image forming apparatus which can prevent the electric discharge when the trailing edge of a recording material passes a transferring position, and yet can stabilize the surface potential of a photosensitive drum. A controller changes a transfer bias voltage Vt during the supply of paper to 0 V before the trailing edge of recording paper arrives at a transferring nip part, changes it to a transfer bias voltage V0 during the non-supply of paper after the trailing edge of the recording paper has passed the transferring nip part, and changes a charging bias voltage to a charging bias voltage smaller than a normal charging bias voltage when an area on the photosensitive drum to which 0 V has been applied passes a charging nip portion. The transfer bias voltage V0 during the non-supply of paper is smaller than the transfer bias voltage Vt during the supply of paper.
    • 一种图像形成装置,当记录材料的后缘通过转印位置时,能够防止放电,并且还可以稳定感光鼓的表面电位。 在记录纸的后缘到达传送压区部分之前,控制器将纸张供给期间的转印偏压电压Vt改变为0V,在非记录纸张期间将其转换为转印偏压V 0 0 < 在记录纸的后缘通过传送夹持部分之后的纸张供应,并且当施加了0V的感光鼓上的区域时,将充电偏置电压改变为小于正常充电偏压的充电偏置电压 通过充电压区部分。 非供纸期间的转印偏压电压V 0 <0>小于供纸期间的转印偏压电压Vt。
