ABSTRACT:
A processor of photosensitive material includes an automatic control system for providing anti-oxidation replenishment, as a function of a stored anti-oxidation replenishment rate and anti-oxidation replenishment provided by exhaustion replenishment. A time interval is initiated during which the anti-oxidation replenishment required due to expired time is compared to the amount of anti-oxidation replenishment provided by the exhaustion replenishment in that time interval. When the difference by which the amount of needed anti-oxidation replenishment exceeds the anti-oxidation replenishment provided by exhaustion replenishment reaches a preset value, a fixed amount of replenisher is added to the developer tank.
