PURPOSE:To easily insert a developing device from above when it is incorporated in a main body by holding the main device body rotatably around one positioning member as a fulcrum, and fixing it with the other positioning member. CONSTITUTION:A grip 157 is fitted rotatably to a support frame 151 and two guide pins 158 and 159 are projected from both flanks at the same positions. Those pins 158 and 159 are fixed to the top frame of the main body side, one pin 158 is fitted in the guide groove 161 of a holding plate 160 as the fulcrum of rotation for the whole of the support frame 151, and the other pin 159 is engaged with an engagement groove 162 recessed in one flank of a holding plate 160 to position the gap between the main body and a photosensitive body 10. Then when the developing device is inserted into the top frame of the main body by holding the grip 157, the pin 159 and the reverse side of the support frame 151 serve as a guide. |
