ABSTRACT:
A photographic processing condition managing method applied to an image forming device equipped with a function for immersing a photosensitive material for photographing into a processing solution for photosensitive materials for photographing so as to process the photosensitive material for photographing. The method includes the steps of: for a photosensitive material for photographing, which has been used for photographing and on which an image has been exposed and which has been immersed into and processed by a processing solution for photosensitive materials for photographing at an image forming device, dividing at least one of the image developed on the photosensitive material for photographing and a portion of the photosensitive material for photographing other than the image into a plurality of colors, and measuring a density of each color, and storing a measured density value of each color, and repeating the steps of dividing, measuring and storing; and determining a state of the processing solution for photosensitive materials for photographing of the image forming device on the basis of an average value of the stored density values, which average value is calculated each time a predetermined period of time elapses. Accordingly, the state of the processing solution for photosensitive materials for photographing can be determined without using a control strip or the like, and can be managed easily and appropriately.
