PURPOSE:To facilitate the work of respective shafts through which the rotating member or the rocking member of a process unit provided in an image forming device is connected to a driving transmitting member in the device and to obtain a connecting means which is easily assembled. CONSTITUTION:Male couplings 10 for attachably/detachably fitting the respective stirring members 7 and 8 and the supply roller 9 of a developing device being a driven side and the respective stirring member transmitting shafts 7a and 8a and the supply roller transmitting shaft 9a of a driving transmitting mechanism part 20 being a driving side, for example, by respectively applying detents to them are provided. A tooth profile 10f formed to be star is provided on the connection part of the coupling 10. On the other hand, the same tooth profile is provided on the shaft hole of each of the stirring members 7 and 8 made of synthetic resin material and meshed with the tooth profile 10f of the coupling 10 so as to transmit driving. Then, a female coupling 11 to which a detent is applied is previously fitted to the shaft of the supply roller 9 made of metallic material, and the coupling 10 is meshed with the same tooth profile, which is provided on the shaft hole, as the tooth profile 10f so as to transmit driving. |
