1. An imaging device comprising:
a photoelectric convertor that includes a first electrode, a second electrode, and a photoelectric conversion layer located between the first electrode and the second electrode, wherein
the photoelectric convertor has a photoelectric conversion characteristic in which a rate of change of the photoelectric conversion efficiency of the photoelectric convertor with respect to a first bias voltage between the first electrode and the second electrode when the first bias voltage is in a first voltage range, is greater than the rate of change with respect to a second bias voltage when the second bias voltage is in a second voltage range that is higher than the first voltage range, and
a first voltage is applied to the first electrode or the second electrode so that a bias voltage between the first electrode and the second electrode exists in the first voltage range.
