An imaging device includes pixels arranged to form columns and each including a photoelectric conversion unit that generates charges by photoelectric conversion, column circuits provided to the columns, respectively, and each receiving a signal from a part of the pixels, a first common control line connected to each of the column circuits, and a control unit that controls the column circuits. Each of the column circuits includes an amplifier circuit whose gain is switchable and a first transistor that controls a current flowing in the amplifier circuit, and the control unit controls the column circuit so that the first transistor supplies a current of a first current value when the amplifier circuit is at a first gain and the first transistor supplies a current of a second current value different from the first current value when the amplifier circuit is at a second gain different from the first gain.
