が生じていた。(Prior Art) A conventional image forming apparatus of this type has a configuration as shown in FIG. The disadvantage was that service costs were high because the operator had to switch the high-voltage output of the charger and adjust the lead ball. In addition, in recent years, so-called process cartridge type copying devices have been commercially available that have a photoreceptor drum, cleaning device, developer, etc. all integrated into one unit, but this type of copying device does not allow for changes in the characteristics of the photoreceptor, each of which has different characteristics. Since the characteristics of the developing device are changed by one control switch, the control range is limited, and the selection of characteristics of the photoreceptor and the developing device is restricted.

It is possible to send a signal to the high voltage power supply and light amount control circuit 15 to control the output of the high voltage power source 16 and the output of the light amount adjustment circuit 17 at the same time. Similarly, by setting the developing cartridge in the direction of arrow B in the copying machine main body, the output of the developing bias power source 2] and the output of the high voltage power source I6 can be controlled simultaneously.

In the table, fluctuations in the halftone potential and dark potential due to fluctuations in the sensitivity and chargeability of the photoreceptor of the photoreceptor cartridge are reduced by controlling the lamp voltage and high voltage power supply output, and differences in developability due to the development cartridge are reduced. It is corrected by controlling the DC component of the bias and the level of the dark potential, and although it is not listed in the table, it is corrected by controlling the DC component of the bias and the dark potential level.
It also controls the N-OFF timing. By switching the control described above, stable image quality can be obtained at all times even if the photoreceptor cartridge or developer cartridge is replaced. This experimental example is an example, and the photoreceptor is OF(
