A usage control device is mounted in an electro-developing type camera with an electro-developing recording medium, by which an image is electronically developed. The electro-developing recording medium has an image recording area and a data recording area. The image is electronically developed and recorded in the image recording area. Data which indicates the number of times that a recording operation of the electro-developing recording medium has taken place, is magnetically recorded in the data recording area. The data recording area is composed of a magnetic recording medium, such as a magnetic tape.
