Abstract: An imaging device having pixels, each pixel including: a photoelectric conversion unit including a first electrode, a second electrode, a photoelectric conversion layer between the first and second electrodes, and a hole-blocking layer between the first electrode and the photoelectric conversion layer. The photoelectric conversion unit is applied with a voltage between the first electrode and the second electrode. The photoelectric conversion unit has a characteristic, responsive to the voltage within a range from a first voltage to a second voltage, showing that a density of current passing between the first electrode and the second electrode when light is incident on the photoelectric conversion layer becomes substantially equal to that when no light is incident on the photoelectric conversion layer.
