A photoelectric conversion apparatus including pixels is provided. Each pixels comprises a photoelectric converter, a floating diffusion, a transfer transistor between the photoelectric converter and the floating diffusion, a reset transistor resetting the floating diffusion, and an amplification transistor outputting a signal from the pixel to a signal line. An accumulation period includes, sequentially, a first period supplying a first voltage to a gate of the reset transistor, a second period supplying a second voltage to the gate, and a third period supplying a third voltage to set the reset transistor to the OFF to the gate. The first voltage is a voltage that falls between the second voltage and the third voltage, the second period is started before the signal is output, and the second period is longer than the third period.
