PROBLEM TO BE SOLVED: To eliminate the cause of run out caused by the fitting or driving of a photoreceptor in an image forming device adopting an electrophotographic method. SOLUTION: This device is provided with a driving shaft 430 to be rotary- driven on a rear side of a rear side supporting blade 410 in freely rotationally, projecting front ward from the rear side supporting blade 410 in piercing through the photoreceptor 100 and projecting the front side of the photoreceptor 100, and a coupling member in the inside position of the photoreceptor 100 of this driving shaft 430. Moreover, the device is provided with a front side tapered frame member 353 and the rear side tapered frame member 460 respectively having tapered surfaces 353a and 460a being symmetrically rotated on the periphery of the rotary axis of the driving shaft 430 while being in contact with a front side flange 102 and the rear side flange 101 constituting the photoreceptor 100. |
