Imaging device

An imaging device comprising:

• a pixel including:
• a photoelectric converter including a first electrode, a second electrode, and a photoelectric conversion layer between the first electrode and the second electrode, the first photoelectric converter generating signal charge,
• a charge storage region coupled to the first electrode, the charge storage region accumulating the signal charge, and
• a transistor having a gate coupled to the charge storage region, the transistor outputting a signal according to an amount of the signal charge accumulated in the charge storage region;
• and
• first voltage supply circuitry configured to supply a first voltage that is negative and a second voltage that is greater than the first voltage, wherein
• the first voltage supply circuitry supplies the first voltage to the second electrode in a first period when the charge storage region accumulates the signal charge, and
• the first voltage supply circuitry supplies the second voltage to the second electrode in a second period different from the first period.
