A driving device controls light emitting thyristors that each include a scanning circuit sequentially driving each of the plural stages of the light emitting thyristors by controlling scanning thyristors. Herein, terminals of each odd numbered stage of the scanning thyristors is commonly connected to a first clock terminal, and terminals of each even numbered stage of the scanning thyristors is commonly connected to a second clock terminal. A control terminal of a first stage scanning thyristor is connected to the second clock terminal, and another control terminal of a previous scanning thyristor is connected to the second control terminal of a subsequent scanning thyristor.
