This X-ray imaging apparatus for rounds includes inside a cart a battery, a charging circuit adapted to limit charging current flowing through the battery, and a control circuit, in which the control circuit includes: a power supply voltage detecting part adapted to detect power supply voltage supplied from an external power supply; a charged voltage detecting part adapted to detect the charged voltage of the battery; a charging current detecting part adapted to detect charging current at the time when the battery is charged; and a charging current value control part adapted to, depending on a variation in the power supply voltage detected by the power supply voltage detecting part, control a charging current value set for the charging circuit.
