<p>Various improvements are made in various parts of an image-forming machine, typically an electrostatic copying machine. (1) Display means (200) for displaying a toner cartridge (179) loaded in the main body (166) of a developing device (34) is provided. (2) Image-forming condition adjusting means is provided for adjusting the image-forming conditions in relation to a toner cartridge loaded in the main body of the developing device. (3) Life signal producing means for notifying the end of the service life of an electrostatographic material (29) is provided which produce a life signal on the basis of a cartridge replacement signal and a final cartridge signal. (4) The life signal producing means produces the life signal on the basis of the final cartridge signal and the final cartridge signal or a predetermined rotation signal whichever is produced earlier. (5) A toner removing means in a cleaning device (36) is held at a non-operating position when a process unit (16) is detached from the image-forming machine and held in a unit holding box (135). (6) When a predetermined number of toner cartridges have been selectively loaded and detached into and from the main body (166) of the developing device (34), loading of a new toner cartridge becomes substantially impossible. (7) When a cartridge has been loaded and detached into and from the main body of the developing device, loading of the same type of a toner cartridge as the one detached from it becomes substantially impossible. d</p> |
