11.5 Drum Temperature Detection Circuit
1) Purpose of the drum temperature detection circuit
Since the photoconductive characteristic of the drum surface varies drastically depending on the
surface temperature of the drum, this circuit detects the temperature of the drum surface to gain the
charging potential according to the environment.
