Abstract

PURPOSE:To make setting of different target potentials on drum easy by using a surface electrometer having the specified measuring window. CONSTITUTION:The measuring window 65 of the surface electrometer 50 mounted to a developing device opposes to the surface of a drum 11 and the printed board 56 which amplifies the voltage detected with an electrode 54 is built in the electrometer 50. When a sensor motor 55 is run, the charges on the drum surface induce voltage in the electrode 54 through the measuring window 64 of a chopper 53. At the time of the surface potentials of diferent modes on the drum 11 are set to respectively different target potentials, the elecrometer 50 will detect the different target potentials at nearly the same values.
