PROBLEM TO BE SOLVED: To provide a radiographing apparatus for obtaining an image of high quality by suitably correcting a dark current of a plane X-ray detector using a semiconductor element. SOLUTION: This radiographing apparatus includes a dark current correcting means for detecting a dark current of the plane X-ray detector using a semiconductor element and correcting an output signal using the detected signal. The apparatus is provided with: a dark current correction command input means for inputting a command to correct a dark current; a dark current change value detecting means for detecting a change in the dark current value; a dark current correction deciding means for deciding that the correction for the dark current is needed when the change value of the dark current exceeds a designated value; and a dark current correction informing means for informing that the correction for the dark current is needed from the dark current correction deciding means.
