Driving device, optical print head and image forming device

An optical print head, comprising:

• a plurality of light emitting elements that are connected in parallel to a common terminal;
• and
• a driving device that drives the plurality of light emitting elements, the driving device includes:
• a scanning circuit in which a plurality of 3-terminal switching elements are arranged, the plurality of 3-terminal switching elements each including a first terminal connected to a first power source, a second terminal connected to a clock terminal, and a control terminal that controls an ON/OFF state between the first and second terminals, that outputs a signal flowing to each of the control terminal to the light emitting elements by ON/OFF switching of the 3-terminal switching elements based on a first clock signal supplied from the clock terminal, and that sequentially scans and drives the plurality of light emitting elements;
• a data driving circuit that drives a driving rectangular wave signal and that supplies a data signal to the common terminal;
• a clock driving circuit that drives a scanning rectangular wave signal and that outputs a second clock signal;
• and
• a differential circuit that generates the first clock signal in which a differential waveform is formed at an edge of the second clock signal by differentiating the second clock signal using an inductor, and that supplies the first clock signal to the clock terminal.
