PROBLEM TO BE SOLVED: To keep the speed of a photoreceptor constant and to obtain a satisfactory image, by constituting a driving device so that the vibration due to the load fluctuation generated in a part to be driven other than the photoreceptor may not be transmitted to the photoreceptor side. SOLUTION: This device is a driving device for transmitting a driving power to the part to be driven other than the photoreceptor through a transmission member 14 which is wound around the driving source 1 of the photoreceptor. An idler 15 is installed, the idler 15 is pressurized so as to maintain the initial tension of the winding transmission member, and the idler 15 is connected to the driving shafts 12 and 13 of the part to be driven through gear trains 16 to 19. |
