PURPOSE:To suppress the play, to reduce an unnecessary vibration of a drum, and to obtain a good copy picture by fitting a shaft to a drum flange by interposing an elastic member. CONSTITUTION:An elastic member 12 is stuck and fixed to one flange 11 of a photosensitive drum 10, and its hole 13 is formed so as to be smaller than the outside diameter of a drum shaft 14. When the drum shaft 14 is inserted from the other flange 15 side and also inserted by force into the hole 13 of the elastic member, a part of its shaft is deformed and pushed into a recessed part 11-0 of the flange 11 and the shaft 14 is held firmly. Accordingly, the play between the shaft 14 and the flange is eliminated, an unnecessary vibration of the photosensitive drum 10 is reduced and a good copy picture can be obtained. |
