A driving method is used in a solid-state imaging device including a plurality of pixel circuits which are arranged in rows and columns, and each of which has a photoelectric conversion unit and a charge accumulation unit and receives a common power source. The driving method includes steps of: reading out, to the outside of the pixel circuit, a photocharge generated at a photoelectric conversion unit in a pixel circuit in a readout row, after resetting a potential of the charge accumulation unit in the pixel circuit to a potential of the common power source while supplying a bias current to the pixel circuit for readout, the photocharge being transferred to the charge accumulation unit as a signal charge; discharging a photocharge generated at a photoelectric conversion unit in a pixel circuit in a discharge row that is to be a readout row later, after resetting a potential of a charge accumulation unit in the pixel circuit to a potential of the common power source, the photocharge being transferred to the charge accumulation unit as an unnecessary charge; and uniformizing a potential of the charge accumulation unit to be reset in the discharging in the case where the discharging is executed following the reading out and in the case where the discharging is executed independently
