摘要： An image forming apparatus includes an image bearing member for bearing a toner image, a rotatable endless belt, a first driving member for rotationally driving the endless belt and in contact with an inner peripheral surface of the endless belt, and a second driving member for rotationally driving the endless belt and in contact with an outer peripheral surface of the endless belt. In addition, a tension detecting unit detects a state of tension of the endless belt and a controller controls a rotational speed of the second driving member. A driving force applied from the second driving member to the endless belt is smaller than a driving force applied from the first driving member to the endless belt, and the tension detecting unit includes a metal roller contacting the inner peripheral surface of the endless belt and detects the tension by movement of the metal roller which follows the endless belt. The controller controls, on the basis of a detection result of the tension detecting unit, the rotational speed of the second driving member so that the state of tension of the endless belt is a predetermined state.

摘要： A circumferential length of a belt is measured within a short period of time. A plurality of marks is provided on a belt. Distances between the marks are set to be all different from each other. The distance between the marks is set to allow the mark to be identified by measuring a period of time between the detection of one mark and that of the next mark even if the length of the belt is changed to some degree by the expansion of the belt or the like. Then, a period of time between the identified mark and the next mark is accurately measured. The total circumferential length of the belt is measured based on the results of measurement.

摘要： The image forming apparatus has a configuration in which a secondary transfer roller guides a leading end of a recording material which enters a secondary transfer nip to be led to the secondary transfer nip and the leading end of the recording material is prevented from coming into contact with a toner image on an intermediate transferring member before the recording material enters the secondary transfer nip. Further, in the image forming apparatus, a surface of a transfer roller is smoothened so that the leading end of the recording material is guided to the secondary transfer nip without being caught. As a result, the present invention is intended to prevent the leading end of the recording material which enters the secondary transfer nip from distorting the toner image on the intermediate transferring member.
