An imaging device having a pixel including a photoelectric converter that converts incident light into charges, and a reset transistor having a first source, a first drain and a first gate, one of the first source and the first drain coupled to the photoelectric converter. The imaging device further including first voltage generating circuity that generates a first voltage; second voltage generating circuity that generates a second voltage, the second voltage generating circuity being different from the first voltage generating circuity; and first switching circuity that causes either the first voltage generating circuity or the second voltage generating circuity to selectively couple to the other of the first source and the first drain of the reset transistor.
