The photoelectric conversion device includes a photoelectric conversion element configured to convert light reflected from an original image to electrical signals and a clock generator configured to generate driving signals for driving the photoelectric conversion element from a reference clock. Each of the driving signals is generated using the same logic gate or substantially the same logic gate.
