IPC: G03G15/08
Filed: 1989-03-31
Abstract: PURPOSE:To always obtain a picture density approximate to a control target value by adjusting a toner concentration for the total photographic developer a little higher than a toner concentration control target value set so as to obtain a proper picture density. CONSTITUTION:A toner concentration for a proper picture density is, for exam ple, 6wt.%, and the control target value is also set at 6wt.%. Warming-up such as raising the temperature of a fixing device is performed from time t0 that a power source is first turned on after developer replacement, and a copying operation is started at the time t1 thereafter; however, the toner concentration comes to 7wt.% immediately after that. The picture density drops by a delay in rising the proper picture density, and it is corrected by adjusting the toner concentration a little higher, thereby obtaining the proper picture density. As time elapses, the toner concentration approaches the control target value; for example, the toner concentration nearly comes to the wt.% of the control target value before or after time t2 that 100 copies are taken.
