Zusammenfassung:A radiation imaging apparatus includes a plurality of pixels, each of which includes a conversion element and a transistor, a plurality of drive lines connected to gates of the transistors, a drive circuit unit configured to supply a voltage to the plurality of drive lines, and a control unit configured to control the drive circuit unit. The control unit performs control of causing the drive circuit unit to apply a different voltage that is between the OFF voltage and the ON voltage and is different from the OFF voltage and the ON voltage to the plurality of drive lines in a different period different from a period in which storage control is performed and a period in which read control is performed.
