An X-ray imaging apparatus implements a fluoroscopy that irradiates a weaker dose of X-rays than a dose on the long-length imaging toward a subject M at each location in the long-length imaging range, while moving an X-ray tube in a body axis direction relative to the subject M prior to the long-length imaging, when the long-length imaging is implemented by moving the X-ray tube 2 in the body axis direction relative to the subject M. The dose D.sub.1 at the location having the thick body thickness is less, so that the tube voltage is set up to be high as the tube voltage V.sub.1 and vice versa, the dose D.sub.2 at the location having the thin body thickness is high, so that the tube voltage is set up to be low as the tube voltage V.sub.2.
