Abstract
An imaging device includes a plurality of pixels and a voltage supply circuit. Each of the plurality of pixels includes: a pixel electrode; a counter electrode; a photoelectric conversion layer located between the pixel electrode and the counter electrode; and a charge blocking layer located between the pixel electrode and the photoelectric conversion layer. The charge blocking layer contains an impurity and has a first surface facing the photoelectric conversion layer and a second surface facing the pixel electrode. The concentration of the impurity on the first surface is higher than the concentration of the impurity on the second surface. The voltage supply circuit supplies a first voltage between the counter electrode and the pixel electrode in a first period and supplies a second voltage different from the first voltage between the counter electrode and the pixel electrode in a second period.
