Abstract
An optical scanning device includes a light emitter, a driver, and a signal outputter. The light emitter emits a laser beam. The driver operates, depending on a signal inputted thereto, in a master state in which the driver performs initialization by reading data from a storage device or in a slave state in which the driver drives the light emitter according to an operation mode corresponding to the signal. The signal outputter outputs the signal to the driver. For the initialization of the driver, the signal outputter outputs a signal for setting the driver to the slave state and setting the operation mode to a specific operation mode. The driver performs the initialization based on a beam intensity of the laser beam emitted from the light emitter driven according to the operation mode based on the signal outputted from the signal outputter.
