摘要： There are provided an image transfer apparatus and an image forming apparatus which can form an image of excellent quality by controlling speed variations of an image carrier and an intermediate transfer body generated by an external force. When the front end of a recording medium enters the nip area provided between the intermediate transfer body and a bias transfer roll and the rear end of the recording medium leaves the nip area, an impact force is applied to the intermediate transfer body and the bias transfer roll. The bias transfer roll swings, due to such impact force, in the direction parallel to the traveling direction of the recording medium to enter the nip area. As a result, a transitional load variation to be applied to the intermediate transfer body with such impact force is absorbed by springs to prevent rotating variation of the intermediate transfer body and the image carrier.

摘要： A detecting unit detects a conveying speed of a conveyer member. A driving unit drives the conveyer member. A first control unit performs a first feedback control of the conveying speed based on detected conveying speed and a predetermined target conveying speed. A second control unit detects a rotation speed of the driving unit and performs a second feedback control of the rotation speed based on detected rotation speed and a predetermined target rotation speed. When a determining unit determines that the detecting unit is anomalous, a switching unit switches from the first feedback control to the second feedback control.
