1. An imaging device comprising:
a charge accumulator that accumulates charges generated by photoelectric conversion;
a first transistor having a first source, a first drain, and a first gate electrode electrically connected to one of the first source and the first drain; and
a first capacitive element that holds the charges and has a first terminal, wherein:
a fixed potential is supplied to the other of the first source and the first drain, and
the other of the first source and the first drain is always electrically connected to the first terminal of the first capacitive element from start to end of an exposure period.
