Abstract

PURPOSE: To prevent the copy miss of many originals independently of contents of originals, by setting the picture density set condition related to the copy picture density to a fixed value on the basis of use information of the original carrying device.
CONSTITUTION: The electrophotographic copying machine is provided with original carrying selection deciding circuit 9 having a function to control selectively control conditions of one of charging voltage control device 10 to photosensitive material 1, exposure light quantity control device 11 to photosensitive material 1, and development bias control device 12 to photosensitive material 1 or their combination. In this case, charging voltage control device 10, exposure light quantity control device 11, development bias voltage control device 12 are provided for designating picture quality control conditions set previously. As a result, copiable picture quality control conditions are determined previously for many originals 3, and picture quality control quality control conditions are selected automatically, thereby preventing the copy miss.
