PROBLEM TO BE SOLVED: To provide a multi X-ray generator and a radiographic equipment, for obtaining an X-ray image of high contrast with a low dosage at high speed by increasing flexibility in selecting a ray-beam quality in an X-ray source and an irradiation position. SOLUTION: The multi X-ray generator provided with a plurality of electron sources arranged in two dimensions and targets arranged in positions opposite thereto includes: a multi electron source including a plurality of electron sources and emitting electrons from the electron sources driven by driving the plurality of electron sources selectively in response to drive signals supplied; and a target portion including a plurality of targets generating X-ray in response to irradiation of the electrons emitted from the multi electron source and outputting X-ray with a different ray-beam quality depending on the generation position of X-ray, wherein the generation position and the ray-beam quality of the X-ray from the target portion are controlled by selective drive of the electron sources in the multi electron source.
