An image forming apparatus includes a first image bearing member for bearing an image, a second image bearing member for bearing an image, an intermediate transfer member, wherein, after a plurality of images are sequentially transferred in a first transfer position and a second transfer position from the first image bearing member and the second image bearing member to the intermediate transfer member, the plurality of images on the intermediate transfer member are transferred to a transfer material, and a detector for detecting a first image for detection and a second image for detection transferred from the first image bearing member and the second image bearing member to the intermediate transfer member, wherein the intensity of the electric field formed in the second transfer position when the first image for detection passes through the second transfer position is smaller (e.g. zero) than the intensity of the electric field formed in the second transfer position when the second image for detection is transferred from the second image bearing member to the intermediate transfer member.
