The present invention relates to an image forming apparatus comprising: an image bearing member; toner image forming means for forming a plurality of toner images on the image bearing member; primary transfer means for superimposing the plurality of toner images on the image bearing member on one another in succession to primary transfer the same to a moving intermediate transfer belt in a primary transfer region; a driving source for moving the intermediate transfer belt through a driving transmitting member with respect to a driving roller which supports the intermediate transfer belt and which moves the intermediate transfer belt; a secondary transfer means for collectively secondary transferring the toner images on the intermediate transfer belt to a recording material; removing means which can abut against and separate from the intermediate transfer belt in a approaching and separating region on the intermediate transfer member and which removes toner on the intermediate transfer belt; and locus varying means which shortens a length of a moving locus from the approaching and separating region of the intermediate transfer belt to the primary transfer region while the removing means is in abutment against the intermediate transfer belt, as compared with a moving locus from the approaching and separating region of the intermediate transfer belt to the primary transfer region while the removing means is separated from the intermediate transfer belt.
