ABSTRACT:
In an electrostatic copying machine, a charging apparatus for a photoconductive member includes a thermally responsive device for automatically adjusting the distance between the corona charger and the photoconductive member in response to temperature changes in the photoconductive member. Therefore, the charge accepted by the photoconductive member is maintained at a substantially uniform level despite the temperature variations of the photoconductive member.
