Disclosed herein is an imaging device including: a pixel unit including a pixel disposed in a plane and a driving unit. The pixel includes an accumulating section configured to detect a physical quantity, and accumulate a charge corresponding to the physical quantity, a transfer section configured to transfer the charge from the accumulating section, a converting section configured to convert the charge into a voltage, an output section configured to output a signal of the voltage converted by the converting section, a reset section configured to reset the potential of the converting section, and a connecting section connected to the converting section. The driving unit is configured to transfer a signal for giving an instruction to transfer the charge, and a connecting signal for controlling connection and non-connection. The driving unit makes the charge transferred in a state of the converting sections being connected to each other.
