PURPOSE:To set the lives of a developing unit and a collecting unit to be optimum and to keep running cost to the minimum by making it possible to respectively separate the developing unit, a toner cartridge and the collecting unit. CONSTITUTION:It is possible to respectively separate the developing unit 16, the toner cartridge 17 and the collecting unit 21. The toner cartridge 17 is fixed to the developing unit 16, and the developing unit 16 in which the toner cartridge 17 is fitted and the collecting unit 21 are fixed to a main body 1 by a specified device so that a gap between the photosensitive drum 18 and the developing roller 24 may be a desired value so as to constitute an electrophotographic processing part. Thus, the life of the electrophotographic processing part is made longer and the running cost is kept to the minimum. |
