ABSTRACT:
A belt driving system having at least one roller for adjusting creep within a plurality of rollers. Creep detecting means provided at one end of the creep adjusting roller is rotated by torque of a flat belt in contact with the creep detecting means. Biasing means for biasing the flat belt toward the creep detecting means and roller-end displacing means for converting the torque of the creep detecting means to displacement of the end of the creep adjusting roller toward a predetermined direction so that the flat belt is moved to the direction contrary to the creep caused by the biasing means are provided. When the flat belt creeps, the creep contrary to the original creep is caused by the roller-end displacing means, and thus the original creep is compensated. Consequently, stable running of the flat belt is obtained and clear pictures of the electrophotographic machine can be also obtained.
