Abstract

An apparatus for processing a photographic sensitive material capable of accurately controlling photographic characteristics and processing solutions. If exposures of images recorded on a negative film have been integrated, for a predetermined number of frames a mean exposure is calculated and a result of comparison thereof with a reference exposure is supplied to the film processor. The result of the comparison is used to control the processing performance of the film processor. A density meter measures the densities of an exposed portion and a non-exposed portion of a color paper processed in a processor portion. As physical quantities affecting the photographic characteristics, the throughput of color paper per unit period, temperature, pH, specific gravity and electric conductivity of processing solutions, quantity of replenishment of replenisher to be replenished to the processing solutions and quantity of water to be added to the processing solutions are detected. If the detected density is out of a predetermined ranger the cause of the measured density being out of the predetermined range is estimated in accordance with the detected physical quantities. In accordance with the estimated causer the quantity of the replenisher to be replenished to processing baths is changed in accordance with the estimated cause so as to make the density of the exposed portion and the non-exposed portion to be included in a predetermined range.
