ABSTRACT:
A method of replenishing a developer during the development of photosensitive plates in a conveyor-type automatic developing machine connected to a replenishing device in which the dissolution of the photosensitive layer in the non-image area of a photosensitive plate is measured with a sensor. The sensor is positioned at a certain point in the developing zone of the machine, and, when the measured dissolution reaches a certain level, the replenishing device is automatically actuated to supply a predetermined amount of replenisher to the developer.
