PURPOSE:To feed easily and inexpensively an electrophotographic sensitive body without deviation and meandering by winding driving belts having the projecting parts to be inserted into holes on the outside peripheral surfaces on plural revolving shafts at least one of which is driven and rotated and providing position control means to control the position of the driving belts in the transverse direction thereof. CONSTITUTION:The four driving shafts 1 are synchronously rotated and the respective driving belts 4 meshed with the shafts 1 are rotated synchronously between the shafts 1 and the driven shafts 3 when a driving motor is operated to rotate an output shaft 7. The belts 4 are subjected to the position control in the transverse direction by belt press plates 2, 2a and therefore the belts rotate without meandering. An electrophotographic sensitive body 5 is rotationally fed while the meandering thereof is corrected by the meshing of the projecting parts 4a and the perforations 6 of the body 5 when the belts 4 rotate. The belts 4 are thus rotated while the position thereof is controlled transversely relative to the shafts 1 without meandering and the body 5 is rotationally fed while the meandering with the belts 4 is always corrected. |
