PURPOSE:To automatically assemble a developing device with high efficiency by easily and surely connecting a rotating member or a rocking member attached to the developing device with a driving transmitting mechanism part. CONSTITUTION:Common couplings 10 are fitted in a 1st stirring member transmitting shaft 7a, a 2nd stirring member transmitting shaft 8a and a supply roller transmitting shaft 9a provided in the driving transmitting mechanism part 20 so as to unitize them. Plural tooth profiles 10f formed to be star are provided on the connection part 10a of the coupling 10. On the other hand, a connecting hole having the tooth profile whose shape is the same as the connection part 10a is provided on the shaft center of respective stirring members 7 and 8, and a supply roller 9 attached to a developing device main body 2. By attaching the mechanism part 20 to the right side surface part 2b of the developing device main body 2, the driving transmitting shafts 7a, 8a and 9a are simultaneously connected to the three shafts of the stirring members 7 and 8 and the roller 9 through the couplings 10. |
