摘要： An image forming apparatus has a transfer material bearing member with a first image bearing member and a second image bearing member sequentially disposed along a conveying direction of the transfer material borne by the transfer material bearing member. A first voltage applying device and a second voltage applying device are positioned to apply voltages to the transfer material bearing member so that the images on the first image bearing member and the second image bearing member are sequentially superimposed and transferred onto the transfer material borne by said transfer material bearing member. A detector is located to detect a current flowing through the transfer material bearing member when a predetermined voltage is applied to an area, on which the transfer material is borne, of the transfer material bearing member before an image transfer is started, and a controller controls the first voltage and the second voltage based on a detected result of the detector.
