The present invention causes the X-ray imaging member (7) of an X-ray imaging apparatus (1), which is provided with a revolution driving device (20) for revolving an X-ray-irradiating member (11) and the X-ray imaging member (7) around a subject (K) with a revolution center line (La) as the center and with a main body-controlling device (400) for controlling the revolution driving device (20), to perform a local movement that differs from the revolving movement with a range of movement in a prescribed direction. The X-ray imaging apparatus is provided with a secondary driving device, which is controlled by the main body-controlling device (400), an electricity-storing means (2) for storing electric power to be supplied to the X-ray imaging member (7), and an electric power supply means (3) for supplying electric power to the electricity-storing means (2). The X-ray imaging member (7) and the electricity-storing means (2) are connected and the secondary driving device causes the electricity-storing means (2) and the X-ray imaging member (7) to move locally as a unit without moving relative to each other. The present invention causes the X-ray imaging member (7) to perform a local movement that differs from the revolving movement to acquire a broad light-receiving surface and limits cable connection failures.La présente invention amène l'élément d'imagerie par rayons X (7) d'un appareil d'imagerie par rayons X (1), doté d'un dispositif d'entraînement en rotation (20) pour faire tourner un élément d'irradiation de rayons X (11) et l'élément d'imagerie par rayons X (7) autour d'un patient (K) avec une ligne centrale de rotation (La) comme centre et d'un dispositif de contrôle de corps principal (400) destiné à contrôler le dispositif d'entraînement en rotation (20), afin de réaliser un mouvement local qui diffère du mouvement de rotation, avec une plage de mouvement dans une direction prescrite. L'appareil d'imagerie par rayons X est doté d'un dispositif d'entraînement
