PURPOSE: To easily execute maintenance work without degrading image quality by positioning a drum shaft part provided so as to project to the outside of a supporting member at a device main body. CONSTITUTION: A hopper 5 and a toner reservoir 9 are placed to align with a receiving member provided in a lower main body 12, respectively. Then, a shaft 10 is inserted into the shaft opening of a drum 1 through a side plate 12a, to position the drum 1. Then, an upper main body 11 is pushed up against the pushing up force of a spring 28 and a hook 27a is engaged with a stopper 27. Therefore, the hopper 5 and the toner reservoir 9 are pressed with the receiving member by a packing 24 respectively and attached in fixed positions. In other words, a unit U is installed in the fixed position. Since the shaft 10 is removed from the side plate 12a, an exchange unit U of consumables can be removed from the device main body. |
