<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus in which rotation transmitting accuracy is enhanced and also the coupling of shafts is facilitated. <P>SOLUTION: A coupling tool 40 has a rotating member 41 screwed and fixed on a driven shaft 33 and integrally rotating with the shaft 33, and a moving member 42 moving in parallel with the shaft center of a driving shaft 34 while rotating in the outer peripheral direction of the rotating member. An inclined surface 41b is formed on the outer periphery of the rotating member 41. When the moving member 42 moves in a direction (b), it applies pressure to the inclined surface 41b of the rotating member, and the parallel surface 41a of the rotating member 41 abuts on the circumferential surface 34b of the driving shaft 34 by the pressure from the moving member 42 and grips the driving shaft 34. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
