摘要：
A method for driving an optical write device, in which a time for formation of a pixel is divided into a plurality of periods, and tone level control based on multi-tone image, data is performed in each of the periods. For example, the time for formation of a pixel is divided by applying a train of pulses with widths weighted in the ratio of 4:2.1, and in each duration of the pulses, a clock signal for 64 tone levels is given.
